Story notes

 * This is the first story to feature Rose in the capacity of the Doctor's companion since Doomsday.
 * Lucius Petrus Dextrus from The Fires of Pompeii says that "she is returning" when seeing the future. This is most likely a reference to Rose's return in this episode.
 * Billie Piper was seen at the end of Partners in Crime, as well as a short cameo in The Poison Sky.
 * Chipo Chung was last seen in the episode Utopia as the Malmooth, Chantho. She plays a human character in this story.
 * This is the 'Doctor-lite' episode of the series, similar to Love and Monsters and Blink.
 * In a trailer seen on BBC One, Donna's grandad looks up to the sky and sees the stars "going out".

Rumours

 * From pictures on YouTube, Donna,  Rose,  Martha, Captain Jack Harkness and Sarah Jane Smith are definitely in this episode. Possible returns from Mickey Smith, Jackie Tyler, Harriet Jones and K-9. The return of Mickey and Jackie has been confirmed via filming photos being posted on Youtube.
 * Enemies likely to be in this episode include Davros and Dalek Caan. Davros was seen in the trailer but in darkness. Several daleks also appeared but whether Dalek Caan was there is unknown.
 * Again, YouTube pictures show that Martha and Captain Jack are talking in a park (confirmed to be in Doctor Who not Torchwood) which could mean that Martha returned to Torchwood with Jack. This may show the cameo appearance of the Torchwood members Gwen and  Ianto
 * In Planet of the Ood when Ood Sigma said "your song will end soon" The Ood sang songs craving to be reunited with each other, and the Doctor's song of craving for  Rose will end soon so he will be reunited with her once more.
 * The Doctor falls into the Medusa Cascade. May be true, because in the Mid-Series trailer it shows the Doctor falling through a blue tunnel
 * The Daleks might begin their appearances in this episode and continue until Journey's End.
 * Harriet Jones will begin in either this episode or the next, her rise to being Prime Minister launching her Global Cleaning process. However, the actual process leads to the world being covered in deadly fumes. Not confirmed in the trailer but if true, then fumes may be part of the series arc.
 * Its been heavily rumoured that Harriet Jones has become evil. She witnessed the events on the Valient and stole the Master's ring. She now uses it to bring back Davros and get revenge on the Doctor.
 * It has been sighted that a red Dalek has appeared. It is either an upgrade to Dalek Caan or an upgrade to Harriet Jones.
 * The Tardis is on fire. The reason for this is unknown but is confirmed in the Trailer.

Continuity

 * In The Sontaran Strategem the Sat Nav kept saying Turn Left. The Doctor is also heard saying Turn Right not Left. This could have something to do with this episode.
 * In "Army of Ghosts", Adeola (Freema Aygeman) tells Matt to go to the left when she is under the control of the Cybermens' earpods. This could also have something to do with this episode.  In fact the phrase "Turn Left" has appeared numerous times in the revived series - this could have been a plan set in by Russell T Davies from the start.

DVD and Other releases

 * This is due to be released in the Series 4 boxset in November 2008 along with the rest of the Series.
