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 comic stories
When the first doctor regenerated into the second in 1966, TV Comic changed the face of the doctor in the comics to suite the change in the show's history, although kept the same companions, the doctor's grandchildren like in the TV series, John and Gillian. They were soon replaced with Jamie McCrimmon, to better match with the TV series of Doctor Who.
