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.
Unfortunately the movie Grandma's Boy is not yet available on HBO Max.
