Michael Dorn only just makes the list for having played Lt Worf in the Next Generation as well as General Worf in the Undiscovered Country movie. He also, bizarrely, played Worf on an episode of the TV series Webster in the episode Webtrek, different show, same character. Two characters isnt much but some may not know that he also holds a credit as Risa Tourist in the Next Generation episode The Captains Holiday. As well as his feature film performances he returned again as Worf in DS9 and managed to make even more of the character. He also played Willie Hawkins in the dream episode as well as various episodes of Family guy as Worf. Various voice roles in computer games are also noted.
