20 Actors Who Played Multiple Roles On The Same Show

In the same 2008 episode of Doctor Who in which Peter Capaldi made his first appearance in a different role, future Marvel movie star Karen Gillan also made her debut on the cult favorite series as a soothsayer who gained psychic powers from breathing in dust from the volcano, Vesuvius. Two years later, the Scottish actress was cast as Amy Pond, who would accompany Matt Smith as the Eleventh Doctor on adventures until 2012.
