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.
Billie Piper
In the autumn of 2003, it was announced that "Doctor Who" would be resurrected in 2005 after a sixteen-year absence from TV; the casting of Piper as Rose Tyler, a travelling companion to the ninth incarnation of The Doctor (to be played by Christopher Eccleston), was announced in May 2004. Piper won the Most Popular Actress category at the 2005 and 2006 National Television Awards for her work on "Doctor Who". BBC News named her one of its "Faces of the Year" for 2005, primarily due to her success in "Doctor Who". At "The South Bank Show" Awards in January 2006, she was awarded "The Times" Breakthrough Award for her successful transition from singing to acting. In March, the Television and Radio Industries Club named her as the best new TV talent at their annual awards ceremony. In September, she was named Best Actress at the TV Quick and TV Choice Awards.
