A back injury at SUNY Cortland ended his athletic career and sent him to Long Island open mics. James spent years working warehouses and training clients while grinding stand-up before a 1996 set at Montreal's Just for Laughs turned industry heads. That exposure led to a development deal and, eventually, King of Queens in 1998. Nine seasons on CBS, a steady friendship with Ray Romano's team, and a workingman-slob formula that the network already knew could print ratings.
His film career spent a decade proving critics right, from Paul Blart: Mall Cop's surprise box office run to a string of Sandler-adjacent comedies that reviewers largely wrote off. The assumption was that James had settled for easy checks over interesting work. Then Solo Mio arrived in 2026 through Angel Studios, landed 81% on Rotten Tomatoes, and reportedly set an all-time record for audience scores on the platform. A 2024 stand-up special, Irregardless, and a 2026 national tour completed the pivot. The comeback arc wasn't supposed to look this clean.
At Ward Melville High School on Long Island, James and Mick Foley wrestled in the same heavyweight class. Foley went to the WWE Hall of Fame. James became a comedian instead. His birth name is Kevin George Knipfing. He borrowed 'James' from a teacher he admired, which is a softer origin story than most stage names get. His brother Gary Valentine is also a comedian. He has four kids, married since 2004, and has increasingly aligned his work with faith-friendly outlets like Angel Studios.
