Frazer Hines
Hines' "Doctor Who" debut came in 1966, when he was cast to play the part of Jamie McCrimmon, the companion of the Second Doctor (played by Patrick Troughton). Originally intended as a one-off guest character, Jamie joined the regular cast and appeared in the series from 1966 to 1969. Hines reprised the role in a cameo in the 20th anniversary serial "The Five Doctors" (1983) and as a guest star in "The Two Doctors" (1985). Hines would appear in 117 episodes of "Doctor Who" in all—more than any other "companion" actor in the history of the series. The only actors appearing in more episodes are those who played the first four Doctors. Many of the episodes featuring Jamie no longer exist in the BBC's collection.
Doctor Who (film)
The film was the first attempt to revive "Doctor Who" following its suspension in 1989. It was intended as a backdoor pilot for a new American-produced "Doctor Who" TV series. It introduced Paul McGann as the Eighth Doctor in his only televised appearance as the character until "The Night of the Doctor" in 2013 (though McGann has portrayed the Doctor also in various audio productions). It also marks the final appearance of Sylvester McCoy as the Seventh Doctor, the only appearance of Daphne Ashbrook as companion Grace Holloway, and the only appearance of Eric Roberts's version of The Master. Although a ratings success in the United Kingdom, the film did not fare well on American television and no series was commissioned. The series was later relaunched on the BBC in 2005. The only "Doctor Who" episodes between the film and the new series were a 1999 spoof, "Doctor Who and the Curse of Fatal Death", and a 2003 animation, "Scream of the Shalka".
