Season 23 of Doctor Who ran between 6 September 1986 and 6 December 1986. It starred Colin Baker as the Sixth Doctor, Nicola Bryant as Peri Brown and Bonnie Langford as Melanie Bush. Though produced as four separate serials from a practical standpoint, it aired as a single, connected serial entitled The Trial of a Time Lord. The season opened with The Mysterious Planet and concluded with The Ultimate Foe.
On 23 September 2019, the season was released on Blu-ray Box Set with updated special effects, extended edits, 5.1 surround sound, BTS studio material, scripts and costume designs, photo gallery, an interview with Bonnie Langford and Matthew Sweet and a revisit to The Doctor Who Cookbook. The story Terror of the Vervoids was also edited into a standalone story. The unique trial scene in the trailer was created by Pete McTighe.
This season had a unique format, never again repeated in the show. Doctor Who had returned to production after a near-cancellation and an eighteen-month production hiatus. For the first time, a season consisted of a single story, The Trial of a Time Lord, although this was made up of four serials from a production perspective: each serial was written by a different person (save for The Mysterious Planet and the first part of The Ultimate Foe, both of which were written by Robert Holmes) and featured a different story presented as evidence, excluding the final two episodes which concluded the ongoing story of the trial; the trial storyline itself acted as a framing device to bracket the first three serials. As a result, whether The Trial of a Time Lord should be considered one story or four has been intensely debated. This single-story format, sometimes referred to as a "miniseries", would later be utilised for the third and fourth series of Torchwood. In an interview in Doctor Who Magazine 448, Timelash author Glen McCoy said that he came up with the idea of the Doctor being put on trial.
The experiment of forty-five-minute episodes having been deemed a failure, the BBC reverted the series to twenty-five-minute episodes, but kept the episode count at fourteen, effectively halving the number of episodes in a season. The last episode, however, ran for thirty minutes. This format lasted for the remainder of the classic series.
This was the final season to feature Colin Baker as the Sixth Doctor; he was fired following its conclusion. He did not return to play the Doctor for the regeneration scene in Time and the Rani, the first story of the following season. It was the last season to use the "neon tubing" logo introduced in 1980. A new arrangement of the Doctor Who theme by Dominic Glynn was introduced this season but was only used for these fourteen episodes, before being replaced by another new arrangement.
The final serial of Season 23 turned out to be veteran writer Robert Holmes's last contribution to the series, falling gravely ill and passing away before he could finish the script. It was then passed to script editor Eric Saward, who tried to finish the script but got into an argument with producer John Nathan-Turner over its ending. Eventually, Saward gave up and quit working on Doctor Who altogether, withdrawing his contributions to Holmes's script as he left. The script was then passed along to Pip and Jane Baker, who completed it as they saw fit.
With this season the BBC returned Doctor Who to an autumn season start for the first time since Season 18; this scheduling would remain for the rest of the original series' run.

Aborted Season 23 Edit
Prior to Doctor Who being placed on hiatus after Season 22, a slate of serials of standard length was planned, and scripts were written for several. The decision to recast Season 23 as a single interconnected arc resulted in production of these stories being cancelled.
Three of the stories were subsequently adapted as Target Books novelisations: The Nightmare Fair (which would have seen the return of the Celestial Toymaker), Mission to Magnus (featuring Sil and the Ice Warriors; Sil ultimately appeared in the Mindwarp segment of the Trial of a Time Lord), and The Ultimate Evil. An unofficial audio adaptation of The Nightmare Fair was also produced for charity in 2003.
Beginning in late 2009, Big Finish Productions launched a series of audio dramas covering scripts that had never made it to production, titled The Lost Stories. The first season featured adaptations of The Nightmare Fair, Mission to Magnus, and other story lines planned for the aborted Season 23.
|1||The Nightmare Fair||Graham Williams||2||Intended return of the Celestial Toymaker. Intended to continue directly from part 2 of Revelation of the Daleks. Eventually adapted into a novel in 1989 and an audio play in 2009.|
|2||The Ultimate Evil||Wally K Daly||2||Eventually novelised in 1989.|
|3||Mission to Magnus||Philip Martin||2||Intended return of Sil and the Ice Warriors. Despite this story's abortion, Sil would still appear in the finalised Season 23, in the story Mindwarp. Eventually adapted into a novel in 1990 and an audio play in 2009.|
|4||Yellow Fever and How to Cure It||Robert Holmes||3||Intended reappearances of the Autons, the Master, and the Rani. Like Sil, the Master would still manage to appear in the finalised Season 23, in The Ultimate Foe.|
|5||The Hollows of Time||Christopher H. Bidmead||2 (original intention)|
4 (altered edition)
|Intended return of the Tractators. Originally developed as 2 45-minute episodes, but altered into 4 planned 25-minute episodes upon hearing news of the 18-month hiatus. Eventually adapted into an audio play in 2010.|
|6||The Children of January||Michael Feeney Callan||2 (original intention)|
4 (altered edition)
|Originally developed as 2 45-minute episodes, but altered into 4 planned 25-minute episodes upon hearing news of the 18-month hiatus. Planned to be adapted into a Big Finish audio play, but rejected in favour of The Macros.|
