Doctor Who has been a staple of pop culture since it debuted in 1963, and hundreds of actors have starred in the show since it began. Many of these actors were veterans of the stage and theater, while others cut their teeth on the show and went on to bigger and better things. Some managed to hit the big time, starring in an assortment of big budget blockbusters.

Many of these actors are well known for playing these large roles, yet less so for starring in Doctor Who. Looking back at their contributions towards Who lore over the last 6 decades can be rather fascinating, as it gives Whovians some insight as to where these popular thespians got their start.

Geoffrey Palmer (Tomorrow Never Dies)

Chisel-jawed actor Geoffrey Palmer had a knack for playing tough-as-nails characters in authoritative positions, which is why he was cast as Admiral Roebuck in the 1997 James Bond flick Tomorrow Never Dies. His character is best remembered for having a verbal punch-up with Judi Dench's character, M.

Palmer previously played an uncredited role in the 1970's "Doctor Who and the Silurians," opposite iconic third Doctor actor Jon Pertwee. He'd return to the series two years later for an appearance in 1972's "The Mutants," and again in "Voyage of the Damned," the 2007 Christmas special co-starring Kylie Minogue.

Donald Sumpter (The Girl With The Dragon Tattoo)

Donald Sumpter is best known to audiences as Maester Luwin in HBO's hit Game of Thrones, but he was an accomplished actor long before that. He's since gone on to star in everything from Black Mirror to the HBO docudrama series ChernobylIn 2011, he co-starred alongside Daniel Craig in the adaptation of The Girl With The Dragon Tattoo, where he played Detective Morell.

The actor got his start in Doctor Who way back in the 1968 Cybermen story "The Wheel in Space," before returning in 1972 to star in "The Sea Devils." Sumpter would return to Doctor Who in 2015, where he played the Time Lord President Rassilon, opposite the twelfth Doctor.

Over-the-top and larger-than-life actor Brian Blessed is best known for playing the bombastic Prince Vultan in the 1980 cult classic Flash Gordon, opposite Max von Sydow and future 007 actor Timothy Dalton.  He'd later make a return to TV, eventually landing a role on Doctor Who in 1986.

There, he played King Yrcanos, a warrior king who fell in love and married the sixth Doctor's companion, Peri. This was revealed at the end of the multi-story epic "The Trial of a Time Lord," where the sixth Doctor faced execution by his own people for a series of grave and serious charges.

Seven years later, Troughton would star in the classic horror film The Omen, where he played the paranoid Father Brennan. His character tries to warn Robert Thorn that his son is the anti-Christ, only to meet his doom when supernatural forces cause him to be impaled by a church spire.
