The War with Grandpa

“Old school vs new cool.”

In a family house where the top floor is a creepy attic, Peter (Oakes Fegley) loses his bedroom the day his Grandpa Ed (Robert De Niro) moves in. He loves the old man, but he wants the room back, so he declares war. Tim Hill sets the prank battle against the attic stairs, Peter's boxes carried up one at a time, while his mother Sally (Uma Thurman) looks on from the hallway below.
