With a recognizable face and dozens of on-screen credits, Kevin Sussman has made a lucrative career out of playing loveable everymen with a nerdy side. He's most widely known for portraying Stuart, the geeky comic-book storeowner, on "The Big Bang Theory" (CBS, 2007- ), which he landed in 2009. Sussman had initially auditioned for the part of Kripke, which ultimately went to his friend and writing partner, John Ross Bowie. Two years later the show's creator, Chuck Lorre, who thought Sussman was perfect for the role of Stuart, called him back to offer him the part. Prior to joining the cast of "The Big Bang Theory," Sussman spent a season playing Betty's boyfriend Walter on the breakout ABC comedy, "Ugly Betty" (2006-10), while also working with some of the most respected directors in Hollywood, including the Coen Brothers, Steven Spielberg and Ang Lee. With a body of work that spans multiple genres and platforms, Sussman has parlayed his versatility and appeal to become one of the most consistent character actors working in Hollywood.
