Jim'll Fix It was a long-running BBC television series hosted by Jimmy Saville. Children from the public would write in to the host requesting that "fix" something for them, to make some wish come true.
Jim'll Fix It was associated with Doctor Who on a number of occasions:
- The Fourth Doctor (Tom Baker) appeared, in-character, during the 1970s, where he handed out torn-off scraps of scarves to give scarves to some girl visitors to the studio.
- Veteran movie actor Peter Cushing (who played Dr. Who in the two cinematic outings) wrote to the show in 1986 to ask if a variety of rose could be named after his late wife.
- Numerous viewers have reportedly written in wishing for a TARDIS of their own or to ride in the Doctor's.
- The Doctor Who mini-episode "A Fix with Sontarans" featuring Colin Baker as the Sixth Doctor came about as a request by a fan named Gareth Jenkins who had his own child-sized version of the Doctor's costume. (Note that a differentGareth Jenkins works with Big Finish Productions).
