Allen Covert is a writer, producer, actor, and constant collaborator with Adam Sandler. He has played small character roles in almost all of Sandler's movies since "Going Overboard" in 1989, which was both actors' first major film. Covert met Sandler while attending NYU. His entry into professional comedy came with a job at the Improv comedy club in Los Angeles, as a doorman. It wasn't until some friends pushed him up on stage one night that his comedy career was born. Covert set out on the stand-up circuit shortly afterwards to hone his skills. Some of his more memorable roles in Sandler films have been the homeless caddy, Otto, in "Happy Gilmore," Sandler's best friend in "The Wedding Singer," and the stoned-out game tester, Alex, in "Grandma's Boy." Covert has also co-written comedy material for Sandler, collaborated on most of the songs on Sandler's album "What's Your Name?," and was one of the screenwriters for "The Benchwarmers." As a key player in Sandler's Happy Madison production company, he has served as producer on 13 films. Covert has also occasionally worked with comedy mogul Judd Apatow, appearing on episodes of "Undeclared" and "Freaks and Geeks."
