Although Paul Campbell is best known for roles such as Billy, Mary McDonnell's loyal assistant, in the Syfy Network's "Battlestar Galactica" and nerdy Billy Morgan, star of NBC's "Knight Rider" reboot, his true passion lies in the world of comedy. Campbell is currently filming the television sitcom "Spun Out" and has recently appeared in the television series "Emily Owens, M.D." and "Almost Heroes." Campbell's credits also include a lead role in Marc Fienberg's "Play The Game" opposite Doris Roberts, Andy Griffith, and Marla Sokoloff, the lead in National Lampoon's "Bag Boy," and a supporting role in "The Big Year" opposite Owen Wilson, Jack Black, and Steve Martin. Equally well-versed in features and television as he is in comedy and drama, Campbell has emerged as one of the most versatile, charismatic actors working today.
