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."
The Two Doctors
This story marked the final appearance of Patrick Troughton as the Second Doctor and the final on-screen appearance of Frazer Hines as Jamie. The Second Doctor appearing much older in this feature, with noticeable grey hair, has been addressed in novelizations and audio books as there having been a significant amount of time passing between "The War Games" (1969) and the Second Doctor's regeneration in "Spearhead from Space" (1970).
