Jeremy Bulloch (born 16 February 1945) appeared as Tor in the Doctor Who story The Space Museum, and in The Time Warrior as Hal the Archer. He is best known, though, for his role in the Star Wars films portraying (but not voicing) bounty hunter Boba Fett.
During the production of The Time Warrior, Bulloch was briefly considered for a role as a companion alongside Sarah Jane Smith. Given the three-month gap between production of The Time Warrior and Invasion of the Dinosaurs, there was, in fact, time to change the scripts to accommodate this hypothetical companion. The idea was tentatively floated to Bulloch by Barry Letts, but it was not vigorously pursued by the production team.
In a 1981 interview with Starlog magazine (issue #50, September 1981), Bulloch claimed to have appeared in the "second story of Dr. Who way back in 1962," and indicated his hope to guest-star on the series again in 1982.
