Arc of Infinity was the first serial of season 20 of Doctor Who. Janet Fielding returned as Tegan in this serial, re-joining the Fifth Doctor and Nyssa on their travels. Colin Baker made his Who debut in this story, playing Commander Maxil. Just over a year later, he would take over as the Sixth Doctor at the end of season 21. Of the several Doctor Who stories filmed outside the UK in the late 1970s-early 1980s, this was the only one to open a season.

Synopsis[edit | edit source]
Omega, an ancient Time Lord made of pure anti-matter, once defeated by the Doctor, is plotting to cross over into this dimension by bonding with the Doctor. Meanwhile, the disappearance of a man in Amsterdam piques the curiosity of his cousin, Tegan, who previously left the Doctor at Heathrow Airport and now finds herself at Omega's mercy. Fearing total destruction from the collision of matter and antimatter, the Time Lords recall the Doctor to Gallifrey to undertake the only viable solution: executing him!
Plot[edit | edit source]
Part one[edit | edit source]
On Gallifrey, a Time Lord is at work, stealing the biodata extract of another Time Lord and killing a technician who stumbles across the crime. The traitor provides the bio-data to a creature composed of anti-matter and uses the bio-data to invade the TARDIS and then the Fifth Doctor's metabolism. The Doctor's companion, Nyssa, helps him recover. The creature is shielded in this attempt by the Arc of Infinity, a curious curve between the dimensions containing quad magnetism which can shield anti-matter. The Doctor decides to head to Gallifrey to track down the supplier of his bio-data, conscious that, unless the creature trying to cross universes is stopped, its incursion could cause a fatal chain reaction to the universe.
During the night, Colin hears something and investigates; he finds a curious birdlike creature, the Ergon, which hypnotises him. A terrified Robin runs away.
The High Council of the Time Lords is also taking the matter seriously and has decreed that the Doctor's TARDIS should be recalled. The Chancellery Guard under the over-zealous Commander Maxil seizes the Doctor and Nyssa. When the Doctor resists arrest, Maxil shoots him...
Part two[edit | edit source]
The Doctor has been stunned to ensure his delivery to the High Council. When he is brought before the High Council the new Lord President, Borusa, is inscrutable while Chancellor Thalia and Cardinal Zorac are openly hostile; only his old friend Councillor Hedin seems pleased to see him.
The President stresses the gravity of the situation since the creature poses such a threat to the Universe, and the High Council has had no alternative but to issue a Warrant of Termination on the Doctor to ensure the creature can no longer bond with him. Fortunately, an old friend, Damon, who is another technician in the records section, provides him with the proof he needs that a member of the High Council stole his bio-data extract.
Meanwhile, the Doctor's former companion, Tegan Jovanka, arrives in Amsterdam looking for her cousin Colin. Instead, she is greeted by Robin, who tells her that Colin has disappeared. When neither of them can persuade the police to take an interest they decide to investigate the crypt themselves.
The Doctor is soon taken for execution, despite Nyssa's attempts to save him, and placed in a dispersal chamber. The sentence is carried out...
Part three[edit | edit source]
The supposed death of the Doctor, however, has not solved the situation. Unbeknownst to the High Council, his mind has been taken into the Time Lord living repository of knowledge, the Matrix, while his body is hidden behind a force shield in the termination cubicle. The creature is a renegade Time Lord, who demands an opportunity to return to the Universe it once inhabited. The truth of the aborted execution is discovered by the wily Castellan, who, while questioning Nyssa and Damon about their involvement, tells them that the Doctor is alive. The Castellan summons and then tells the High Council.
Tegan and Robin are attacked by the Ergon's weapon, a matter converter, and transported into a TARDIS hidden at the Frankendael and belonging to the renegade. Their minds are scanned, revealing to the creature that Tegan knows the Doctor. The renegade uses Tegan as bait to force the Doctor to obey him, also releasing Colin from his slavery as a reward. The Doctor is returned to normal space on Gallifrey where he makes for the High Council Chamber. Lord President Borusa has fallen under suspicion of being a traitor because the Castellan reveals it was his codes that were used to transmit the bio-data. The truth, however, is that Hedin is the traitor. He is in awe of his master - the mighty Omega, first of the Time Lords and pioneer of time travel.
Hedin wishes to release Omega from his exile in a universe of anti-matter, not realising the great Time Lord has been driven mad by his years of solitary confinement. The Castellan kills Hedin, but this does not prevent Omega using the Arc of Infinity to seize total control of the Matrix and, therefore, the organisation of Gallifrey...
Part four[edit | edit source]
Fortunately, the Doctor and Nyssa manage to slip away and return to the TARDIS. They use the scant knowledge provided by Tegan to determine that Omega has established his base in Amsterdam on Earth, and head there immediately, desperately trying to find the Frankendael crypt she described. After a lengthy hunt, they find the lair defended by the Ergon, and Nyssa disposes of it with its own matter converter. They reach Omega's TARDIS at the point at which both the ship is destroyed and Omega makes full transference to Earth using the Arc of Infinity. When he peels his decayed mask away he reveals the features of the Doctor.
Omega heads off into Amsterdam with the Doctor, Tegan and Nyssa in hot pursuit. Within a short time, the Doctor's prediction of an unstable transfer begins to come true: Omega's flesh decays and it is clear his new body is not permanent. When the Doctor, Tegan and Nyssa catch up with him it is a painful task for the Doctor to use the Ergon's matter converter on Omega, expelling him back to his own universe of anti-matter. The Time Lord High Council on Gallifrey detects the end of the threat.
Once Tegan has checked on her cousin's progress in hospital, she decides to rejoin the TARDIS crew. This time it is as a willing traveller.

References[edit | edit source]
Biology[edit | edit source]
- To remain in our universe, Omega needs to bond with a Time Lord, reversing his polarity. To that end Hedin steals and transmits the Doctor's biodata extract.
The Doctor[edit | edit source]
- Reference is made to the Doctor's failure to return Romana II to Gallifrey after she joined him on his quest to collect the Key to Time.
- After finding himself "vaporised", the Doctor appears in the Matrix.
Individuals[edit | edit source]
- Tegan has lost her job as an air stewardess and was hoping that meeting Colin Frazer, her favourite cousin, would cheer her up.
- Damon tells the Doctor that his former companion Leela is well. The Doctor is sorry to have missed her and Andred's wedding.
- One guard alerts Maxil to the Doctor and Nyssa's presence, while another tries to arrest them.
Influence[edit | edit source]
- Frankenstein - The scene of Omega at the Punch and Judy show and interacting with a child was inspired by the 1931 film, as well as The Bride of Frankenstein.
Species[edit | edit source]
TARDIS[edit | edit source]
- The Doctor is recalled to Gallifrey. Once there, his TARDIS is incapacitated by the removal of the main space-time element from under the console, although Damon later replaces it with one without a recall circuit.
- Maxil removes the heart of the TARDIS (or part of it).
- The Doctor repairs the audio system of his TARDIS. Nyssa says it needs some other repair work after it was damaged by the Cybermen: in her opinion, in particular, the navigation system and the state of temporal grace (which failed during the Cybermen attack on the TARDIS).
- Omega has acquired a TARDIS.
Technology[edit | edit source]
- The fusion booster is a piece of equipment from Gallifrey, capable of an enormous conversion rate over very short periods and fuelled by anything that contains hydrogen atoms.
- The Time Lords use impulse lasers.
Time Lords[edit | edit source]
- Borusa has regenerated again and is now Lord President. When he meets the Doctor, Borusa notes that he has also regenerated.
- The Castellan mentions that the destruction of a Time Lord has only been ordered once before. Previously, Morbius was ordered destroyed.
- A sound similar to a Cloister Bell is heard when the execution of the Doctor is to be performed.
Story notes[edit | edit source]
- Peter Davison also played Omega in part four when Omega's body becomes a replica of the Doctor's, but was credited on-screen only as "The Doctor".
- Sean Arnold and Patrick Stewart were considered for the role of the Castellan; Glyn Owen, William Lucas and Maurice Denham were considered for Hedin; and Pierce Brosnan was considered for Maxil. Colin Baker was cast as Maxil after assistant floor manager Lynn Richards recalled seeing Baker in "City at the Edge of the World", a 1980 episode of Blake's 7. (TCH 36)
- Maya Woolfe (Hostel Receptionist) is credited as "First Receptionist" in the combined Radio Times cast for parts three/four.
- Crowd control in Amsterdam proved to be a major issue throughout the shoot, with Dutch viewers recognising Peter Davison from All Creatures Great and Small. John Nathan-Turner tried to assist Ron Jones in dealing with the onlookers, and indeed is visible in the transmitted version of Arc Of Infinity, shooing away a group of gawkers in the background of the episode four scene in which the Doctor and Nyssa use a telephone box. At one point, Nathan-Turner's attempts at crowd control became dangerous when an elderly woman assumed he was a thief and attacked him.
- The Dutch street organ that transfixes Omega for a moment during part four is playing the song "Tulips from Amsterdam". The same music is heard during the establishing shot of Amsterdam at the start of part one.
- Ian Collier takes on the role of Omega, originally played by Stephen Thorne in TV: The Three Doctors. To keep the return of Omega a surprise, Collier was billed in the end credits as "The Renegade" for parts one and two, with the billing becoming "Omega" for parts three and four.
- The Radio Times programme listing for part one was accompanied by a black and white head-and-shoulders photograph of Lord President Borusa and the Doctor labelled "New Season", with the accompanying caption "Summoned to Gallifrey, planet of all time lords — the Lord President tells the Doctor of his future: 6.45".
- Every story during Season 20 featured a component of a story from the show's past. For this serial, it was Omega, who last faced the first three incarnations of the Doctor in the tenth-anniversary story. (TV: The Three Doctors)
- Tegan is the first companion to have rejoined the Doctor on his travels after having departed, although other companions/recurring characters had previously left the Doctor's company then reappeared, though she only departed in the previous story. (TV: Time-Flight)
- Tegan, while playing a significant part in the serial, has no scenes on Gallifrey, thus does not interact with half of the guest cast.
- John Nathan-Turner nicknamed Colin Baker "Archie", because he thought he gave "the archest performance he's ever seen in rehearsal". Baker had to remove his elaborate helmet as it kept bumping into doorways and arches, so he spent most of the story with the helmet under his arm, against his hip. He later said it felt like he was carrying a chicken around, and took to calling it "the chicken".
- The story was originally set in London.
- The original storyline involved the Doctor suffering nightmares about his regeneration, which were actually a precursor to the arrival in our universe of an entity called the Avatar, who takes on the Doctor's form and goes to Amsterdam. Operating there as Neman, the Avatar begins to take control of human minds, striving to create a form in which it will be able to permanently maintain its existence. The Doctor and Nyssa discover Neman's plot when they land in a future version of Amsterdam, which is populated by robot guards called Sweepers, the elderly Resisters, and barbaric Anarchs. Realising that history has been altered, they travel back in time to present-day Amsterdam. There, the Doctor discovers that Time Lord regeneration is the mechanism by which the Avatar is made manifest. The Avatar is defeated when the Doctor relives his own recent regeneration.
- Colin Baker was originally considered for the Castellan.
- It was Ian Levine who suggested the inclusion of Omega,
- Cardinal Zorac was originally called Zoral.
- While visiting Amsterdam's Red Light District, Janet Fielding was mistaken for a prostitute.
- Filming was allowed in Amsterdam so long as the story didn't involve drug smuggling, prostitution or diamond theft.
- Colin Baker played Maxil not as a guest role, but as someone who thinks he's starring in his own series. As a result, John Nathan Turner had to tell him that "It's called Doctor Who, not The Bloke Who's a Guard in the Background".
- Colin Baker was a fan of the show and delighted to play a guest role, but was also disappointed that this meant that he could never play the Doctor.
- When Colin Baker was offered the role of Maxil, he was doing a play in Brighton.
- Colin Baker jokes that while filming the scene where Commander Maxil shoots the Doctor, he was gunning for Peter Davison's part. Davison claimed that Baker enjoyed the scene a bit too much.
- Sarah Sutton ripped her trousers during the crypt scene.
- Ian Collier described Omega's costume as one of the most uncomfortable experiences of his life.
- Ian Collier got burned filming the exlosives scenes. They used metal plates to cover the charges.
- Peter Davison claimed that he was planning to use a dildo he purchased in Amsterdam as a weapon to kill Omega, but because they were running behind schedule, he didn't get a chance.
- The cast found the Ergon costume laughable. Eric Saward claimed it was neve described in the script and thought it was "lunatic" when he saw it. Johnny Byrne claimed it was a legitmate, "less successful attempt" at biosynthesis.
- John Nathan-Turner never explained why he wanted Tegan back or left her behind. Eric Saward thought it was contrived, while Peter Davison thought it was a "ludicrous coincidence".
- Sarah Sutton grew to dislike running around in Amsterdam, especially after three days of it.
- Eric Saward claimed that John Nathan-Turner wanted to film in Amsterdam for no rhyme or reason and that all you could do is run around the streets.
- Leela had been written into the script, but Louise Jameson was not available. A few of Leela's actions critical to the plot were therefore given to Nyssa, resulting in a slightly unusually aggressive role for the character.

Myths[edit | edit source]
- New regular costumes for Nyssa and Tegan are seen for the first time in this story. (Although Tegan's new costume makes its debut here, Nyssa's is not seen until the following story, Snakedance. This myth derives from the fact that numerous publicity photographs of the two actresses wearing their new costumes were taken during Arc of Infinity's location shoot in Amsterdam. These photo shoots were made possible by the fact that Snakedance was completed before Arc of Infinity.)

Home video and audio releases[edit | edit source]
DVD releases[edit | edit source]
This story was originally released in a double-pack with Time-Flight in Region 2 and 4 but released singly in Region 1.
The R2 and R4 cover art of this story and Time-Flight shows the "Peter Davison Years" as 1981-1984. All other Davison-era releases have claimed the years as 1982-1984 in deference to the January 1982 broadcast of Castrovalva. However, there is justification for calling the era 1981-1984, as that's the period of time Davison actually worked on the programme. Like Jon Pertwee, Davison fell victim to the BBC's decision to push back the premiere of his first series to the start of the new calendar year. Neither actor is generally credited for their first year on the job, making their eras appear a little shorter than they actually were. While Pertwee only filmed about half of Season 7 in 1969, almost everything of Season 19 was filmed in 1981. Indeed, Davison's first work on the series — his regeneration scene — had been filmed on 9 January 1981, almost a full year prior to the release of Castrovalva. Ironically, the only part of Davison's initial year not filmed in 1981 was Time-Flight, the only other DVD release to bear the claim of an era lasting from 1981-1984. All told, Davison's time in front of the cameras as the Doctor lasted from 9 January 1981 to 12 January 1984 — almost precisely the three-year tenure he had been advised by Patrick Troughton to undertake.
