The following constitute extras to the principal cast, i.e. those without speaking parts.
TV pays more to those with speaking parts, so names are either here or the cast page - not both.
While some names appear here more than once, some artistes (Terry Walsh and Alan Chuntz for instance) were regular stunt performers on the programme and so re-used frequently.
| Michael Brinker | Kaled Soldier |
| Anthony O'Keefe | Kaled Soldier |
| Steven Butler | Kaled Soldier |
Presumably these are the Kaled Soldiers on location.
| Alan Chuntz | Kaled Soldier in Ravon's HQ |
On the phone when The Doctor disarms the general!
| Peter Kodak | Elite Guard |
| Giles Melville | Elite Guard |
| Barry Summerford | Elite Guard |
| Bob Watson | Elite Guard |
| Roy Caeser | Elite Guard |
| Alan Chuntz | Elite Guard |
| Jim Dowdall | Elite Guard |
Generally, there were about four of the above per episode. Alan Chuntz, a regular stuntman, bearing more than a passing resemblance to Charles Asnavour, takes part in the armoury fight, probably with Jim Dowdall, another famous stuntman. Barry Summerford appeared in the Zammo McGuire era of Grange Hill.
| Anthony Lang | Kaled Councillor |
| Ronald Nunnery | Kaled Councillor |
| George Romanov | Kaled Councillor |
From Episode Three as sidekicks to Mogran. Anthony Lang is the ascetic-looking Time Lord in the first episode of The Three Doctors.
| William Ashley | Kaled Scientist |
| Richard Orme | Kaled Scientist |
| John Timberlake | Kaled Scientist |
| Patrick Travis | Kaled Scientist |
| Alan Charles Thomas | Kaled Scientist |
| Charles Erskine | Kaled Scientist |
| Tony Hayes | Kaled Scientist |
| Charles Rayford | Kaled Scientist |
| Mike Reynell | Kaled Scientist |
| Paddy Ryan | Kaled Scientist |
| Harry Van Engel | Kaled Scientist |
| Terry Walsh | Kaled Scientist |
Plenty of those though, in the last episode, there are only about half a dozen to get exterminated. Tony Hayes plays a Mentiad in Pirate Planet. Paddy Ryan plays the First Werewolf (you know, the one on the moors) in John Landis’ American Werewolf in London. Terry Walsh is the suspiciously burly scientist (surely an engineer!) in the armoury fight scene.
| Paul Burton | Kaled Boy |
Presumably one of the troops that pull The Doctor and Harry out of the gas attack. Paul went on to play Tom Brown in Royal Flash.
| Ken Tracey | Kaled Prisoner |
The other Kaled in the Thal Dome.
| David Billa | Thal Soldier |
| Timothy Blackstone | Thal Soldier |
| David Cleeve | Thal Soldier |
| Kirk Clugston | Thal Soldier |
| Julian Peters | Thal Soldier |
| Douglas Rossiter | Thal Soldier |
| Terry Walsh | Thal Soldier |
Terry Walsh is the Thal in the green helmet with the torch, alongside Pat Gorman capturing Sarah and Severin, but he also seems a likely choice as one of the soldiers that attack the trench in Episode One. Timothy Blackstone was a regular in "blue" films at the time, appearing in 1970s hardcore porn shorts such as Desire, Non-Stop Spunker and Gypsies Curse. The brother of Baroness Tessa Blackstone, he was convicted of insider trading in 2003.
| David Cleeve | Thal Guard |
| Patrick Scoular | Thal Guard |
| Terry Walsh | Thal Guard |
| Jim Dowdall | Thal Guard |
| Dinny Powell | Thal Guard |
Dinny Powell comes from a large family of stuntmen, and doubled for both Sean Connery and Roger Moore as James Bond. Terry Walsh is the guard that gets very neatly punched unconscious during the silo escape.
| John Dunn | Silo Cart Driver |
| Keith Norrish | Thal Officer |
| David Roy Paul | Thal Officer |
| Philip Mather | Thal Officer |
| Eric Rainer | General |
| John Beardmore | General |
| Peter Whitaker | Thal Politician |
From Episodes Three and Four when the rocket went up. Keith Norrish was a federation Trooper in Blake’s 7, while David Roy Paul was a Crimo. John Beardmore gets ‘eaten by the ground’ as Captain Revere in the first minutes of Frontios. Peter Whitaker was another Mentiad, and Inspector Gascoigne in The Faceless Ones.
| David Billa | Thal Survivor |
| Timothy Blackstone | Thal Survivor |
| Les Conrad | Thal Survivor |
| Reg Turner | Thal Survivor |
From Episodes Five and Six, blowing up the Bunker; some presumably are intended to be civilians. David Billa went on to play a Vogan.
| Stephen Calcutt | Muto |
| John Delieu | Muto |
| James Muir | Muto |
| Roger Salter | Muto |
| Terry Walsh | Muto |
Stephen Calcutt played one of the Shadow’s Mutes in Armageddon Factor, as well as standing in for Peter Mayhew and David Prowse in Star Wars. James Muir played a number of minor parts in Dr Who, including a detective in City of Death. Terry Walsh, having played two Thals and a Kaled, now completes the set by playing a Muto!
| Dod Watson | Thing |
Crawling past the grille on the way to the Cave of Mutations.
