Known to many as the guy who appears in all the Adam Sandler movies, Allen Covert grew up in Florida and went to college in New York, where he met Sandler while working at a restaurant. After trying his hand at improv, he became steadily more interested in comedy, and began to collaborate with his friend Sandler, helping write the material for Sandler's comedy albums and eventually appearing in his films.
Covert has subsequently appeared in almost all of Sandler's movies, beginning with 1989's Going Overboard (also known as Babes Ahoy). His appearances have ranged from small cameos to major supporting roles, and he even gained 40 lbs. to play Sandler's roommate in Little Nicky. The comedian has also worked as a writer, producer, and actor on his own, for movies like 2006's Grandma's Boy and 2008's Strange Wilderness. ~ Cammila Albertson, All Movie Guide.
