# Doctor Who season 6

The sixth season of British science fiction television series Doctor Who began on 10 August 1968 with the first story of season 6 The Dominators and ended Patrick Troughton's reign as the Doctor with its final story The War Games. Only 37 out of 44 episodes are held in the BBC archives; 7 remain missing. As a result, 2 serials are incomplete: only episode 2 of the 6-part story The Space Pirates still exists, while The Invasion has had its two missing episodes (episodes 1 and 4) reconstructed using animation.

## Casting
### Main cast

* Patrick Troughton as the Second Doctor
* Frazer Hines as Jamie McCrimmon
* Wendy Padbury as Zoe Heriot
Patrick Troughton, Frazer Hines and Wendy Padbury make their final regular appearances as the Second Doctor, Jamie McCrimmon and Zoe Heriot respectively. Troughton and his fellow actors collectively decided that the workload of Doctor Who was exhausting them, and that they would soon depart from the show. From Season 7 onwards the show would never have such a high number of episodes again. The three actors remained with the show until the conclusion of the final season six serial The War Games.
Troughton reprised his role in three subsequent special stories, one of which also featured Hines.

### Guest stars

Nicholas Courtney reappears as Brigadier Lethbridge-Stewart in The Invasion, last seen (as a Colonel) in The Web of Fear. He would soon make regular appearances in the program beginning with season 7's Spearhead from Space.
John Levene makes his first appearance as Corporal Benton in The Invasion. He would continue to make regular appearances, with the character promoted to sergeant, from season 7 until season 13.
Alan Bennion makes his first of three appearances in the series playing an Ice Warrior. In this, his first appearance, he portrays Lord Slaar in The Seeds of Death.
Kevin Stoney makes his second appearance as a villain in The Invasion as Tobias Vaughn. Louise Pajo and Ronald Leigh-Hunt guest star in The Seeds of Death.

## Serials

Terrance Dicks took over from Derrick Sherwin as script editor from The Invasion, with Sherwin resuming the role for The Space Pirates. Derrick Sherwin took over as producer from Peter Bryant for The War Games.
Season 6 is the most complete of all the Second Doctor's seasons, with only seven episodes missing (compared with thirty-three from Season 4 and eighteen from Season 5), none of the season's stories missing in their entirety and only two stories (The Invasion and The Space Pirates) incomplete. This compares to the first two seasons of the Second Doctor from which only two complete serials (The Tomb of the Cybermen and The Enemy of the World) survive. The missing two episodes of The Invasion have since been reconstructed using animation and released on DVD.
The War Games, which was the final serial of the season, and the last of Patrick Troughton's tenure as the Doctor, was also the second longest serial up to that point, spanning 10 episodes – only the 12-part serial The Daleks' Master Plan from Season 3 was longer. Both of these would be beaten in 1986 by the 14-part season-spanning story The Trial of a Time Lord
The Dominators and The Mind Robber were both produced at the end of the fifth recording block and held over to Season 6.

| On an alien planet, the Doctor uncovers a plot to conquer the Galaxy with brainwashed Earth soldiers, forced to fight in simulated "war games", reflecting the periods in history whence they were taken, with the aliens being aided by a renegade Time Lord called the War Chief. Joining forces with rebel soldiers, who have broken their conditioning, the Doctor and his companions foil the plot and end the fighting. The War Chief is killed when the aliens' leader, the War Lord, realises he has been plotting against him. The Doctor needs the help of the Time Lords to put things right, but risks capture for his interference across space-time and the theft of his TARDIS. The Time Lords return the soldiers to Earth, dematerialise the War Lord, erase Zoe and Jamie's memories from the points in time when they first entered the TARDIS and then return them there. They then place the Doctor on trial; who cites his many battles against the evils of the universe. Accepting this defence, the Time Lords exile him to Earth, and tell him he will change his appearance. He cries out indignantly as a forced regeneration is triggered. ||||||||||
