12 Actors You Probably Forgot Were On Heroes
7. Michael Dorn
Who He Played: The oft-mentioned, little-seen President of the United States in Season 3.
Where You Know Him From: As Worf on Star Trek: The Next Generation.
Why You Forgot He Was On Heroes: Like Ray Park, many casual viewers likely had no idea that the man who played the President and the man who played Worf were one in the same. Though he's had a lucrative career in film, television and video games, many will forever remember him as the noble Klingon.
Heroes didn't do much to give Dorn something to chew on, either, as the character only made brief appearances, with his off-screen actions - including issuing the round up of superhumans and, later, stopping it in favour of funding a new Company - having more effect than the time he actually had on-screen.
