The Box of Delights (TV series)
Patrick Troughton was a familiar face on BBC TV from playing the Second Doctor in "Doctor Who"; a contemporary "Blue Peter" feature on the drama makes the connection that in the role of Cole Hawlings, the kindly Punch and Judy Man, Troughton was playing another mysterious, scruffy time traveller. Renny Rye noted that Troughton "who was my favourite Doctor Who...had a quality that is unsurpassed, I think, as someone to pull you into a tale."
Second Doctor
Due to what would appear to be continuity errors in Troughton's later appearances (particularly in "The Two Doctors"), some fans have speculated that the Time Lords used the Second Doctor as an agent after the events of "The War Games" (1969), and that he did not in fact immediately regenerate and enter his exile on Earth. This theory of continuity is described as "Season 6B". Additionally, while "The War Games" never depicted the Doctor's regeneration itself, it was later depicted in "TV Comic", which treated the exiled Doctor's exploits on Earth, before, in a comic entitled "The Nightwalkers", showing the Doctor dragged in to the TARDIS by animated scarecrows, allowing his change of appearance to take place. The Second Doctor's regeneration was also depicted in "Devious", a fan-produced film starring Jon Pertwee in his last appearance as the Third Doctor.
