Grandma's Boy

Grandma's Boy is a movie starring Allen Covert, Linda Cardellini, and Shirley Jones. A thirty-five-year-old video game tester has to move in with his grandma and her two old lady roommates.
Even though he's 35, Alex acts more like he's 13, spending his days as the world's oldest video game tester and his evenings developing the next big Xbox game. But when he gets kicked out of his apartment, he's forced to move in with his grandmother.
