The lead character was listed as "Doctor Who" for the last time for the next twenty-four years. Beginning with Doctor Who: Castrovalva: Part One (1982), until the series' cancellation in 1989, the character was credited simply as "The Doctor" at the request of Peter Davison. Doctor Who (1996) did not have an on-screen character name credit for either the Eighth Doctor or Seventh Doctor; however, the press kit for the film credits them as "The Doctor" and "The Old Doctor" respectively. The 2005 relaunch reverted to using "Doctor Who" until switching again to "The Doctor" at David Tennant's request, starting with Doctor Who: The Christmas Invasion (2005).
This is the first regeneration story to credit both the departing and succeeding actors playing the role of the Doctor. Patrick Troughton and Tom Baker were not credited for their appearances in The Tenth Planet and Planet of the Spiders respectively, while Jon Pertwee did not appear at all in The War Games. This also happened at the end credits of The Caves of Androzani, The Parting of the Ways, The End of Time, The Night of the Doctor and The Time of the Doctor. In both of the first two instances, Peter Davison received second billing.
This serial arguably - as pointed out in About Time 5 by Lawrence Miles and Tat Wood - has the largest body count of any Doctor Who story, albeit not graphically shown, as the destruction of Logopolis apparently causes a significant portion of the entire universe to be swallowed by a wave of entropy. At the very least, the Traken Union is destroyed, which would put the death toll in the billions and make the Master a mass killer on an unprecedented scale, albeit not by intent. The Last Great Time War potentially had a higher body count, but even were a death toll to be given, it occurred off-screen.
The usual image of Tom Baker's face (and by extension, much of the starfield footage in the closing credits) was electronically blurred as a method of signifying his departure, and the titles & credits were re-shot with Peter Davison's face for the following story, Doctor Who: Castrovalva: Part One (1982).
It was John Nathan-Turner's idea to use clips of the Doctor's friends and enemies. Ian Levine assisted in finding clips. The villains montage included the skeletal Master (from The Deadly Assassin), a Dalek (Destiny Of The Daleks), the Captain (The Pirate Planet), the Cyberleader (Revenge Of The Cybermen), Sontaran Commander Stor (The Invasion Of Time), the Zygon Broton (Terror Of The Zygons), and the Black Guardian (Doctor Who: The Armageddon Factor: Part Six (1979)). The companions montage featured Sarah Jane Smith (from Terror Of The Zygons), Harry Sullivan (The Sontaran Experiment), Brigadier Lethbridge Stewart (Invasion Of The Dinosaurs), Leela (The Robots Of Death), K-9 (The Armageddon Factor), the original incarnation of Romana (The Stones Of Blood), and the second Romana (Full Circle).
