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."
Jon Pertwee
In 1969, Pertwee was selected by outgoing producer Peter Bryant and the series' next producer, Derrick Sherwin, to take over as the Doctor from Patrick Troughton in the television series "Doctor Who". Pertwee had asked his agent to apply for the role for him and was surprised to find he was already on the shortlist. He was the second choice for the role of the Third Doctor; Ron Moody was the first but was unavailable.
