3. Matthew Perry - Benny (Fallout: New Vegas)
http://www.youtube.com/watch?v=vv-6L8UoLkc Could this be any more surprising? Matthew Perry a.k.a Chandler Bing made an appearance in one of the better open-world games we've seen in the last five years. Fallout: New Vegas (2010) is a post-apocalyptic open-world RPG in which you play the role of a courier who is attacked when delivering a package and left to die. Your main quest involves finding your attempted murderer but then you get dragged into a whole, rather unfortunate series of events. Eventually, you find out that the man who attacked you is a named Benny who wears a black and white chequered suit. Perry was a huge fan of Fallout 3, and when appearing on Ellen Degeneres' show with a signed copy of the game to show his love for the franchise, Obsidian hired and casted him as New Vegas' secondary antagonist.
