Season 6

Season 6 of Doctor Who ran between 10 August 1968 and 21 June 1969. It starred Patrick Troughton as the Second Doctor, Frazer Hines as Jamie McCrimmon and Wendy Padbury as Zoe Heriot. The season opened with The Dominators and concluded with The War Games.

Overview
It consisted of forty-four episodes which made up seven serials. This season featured the first ever UNIT story, The Invasion, which showcased the return of Brigadier Lethbridge-Stewart.

It also featured the first official appearance of Time Lords and the as yet unnamed Doctor's home planet (another member of Susan and the Doctor's race, the Monk, had appeared previously, but without much elaboration and without using the term "Time Lord").

It also marked the tenure of Patrick Troughton as the Second Doctor. It consisted of seven serials and forty-four episodes, including two epic-length storylines: the eight episodes of The Invasion and the ten-episode The War Games.

This season was the last to be filmed in black and white. Season 6 is also the last season of Doctor Who to contain missing episodes, with all subsequent seasons affected by the then-in-effect junking policy restored through various means.

This season is, fortunately, more complete than the previous three seasons, of which only five serials exist. Seven episodes from this season are lost, although audio recordings remain for all; as a result, the DVD release of The Invasion used animation to recreate the two missing episodes from that story. To date, it is the most complete season of the Patrick Troughton-era.
