An actor with a talent for playing the goofy guy, Derek Richardson began his career making appearances on shows like Strangers with Candy and Felicity. He played the young version of Harry Dune in the Dumb and Dumber prequel, Dumb and Dumber: When Harry Met Loyd, before being cast in the sadistic horror flick Hostel. He was nominated for an MTV Movie Award in the category of Best Frightened Performance for the role, and the notoriety helped him snag his next part, the role of Patrick Bachelor on the hit dramedy Men in Trees.
