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."
Sylvester McCoy
McCoy became the Seventh Doctor after taking over the lead role in "Doctor Who" in 1987 from Colin Baker. He remained on the series until it ended in 1989, ending with "Survival" (see List of Doctor Who episodes (1963–1989)). As Baker declined the invitation to film the regeneration scene, McCoy briefly wore a wig and appeared, face-down until the last moment before the regeneration commenced, as the sixth Doctor. He played the Doctor in the 1993 charity special "Dimensions in Time", and again in 1996, appearing in the beginning of the "Doctor Who" television movie starring Paul McGann as the Eighth Doctor.
