The War With Grandpa follows Peter (Oakes Fegley) and his Grandpa Jack (Robert De Niro). The two used to be very close but when Grandpa Jack moves in with the family, Peter is forced to give up his most prized possession: his bedroom. Peter will stop at nothing to get his room back, scheming with friends to devise a series of pranks to drive him out. But Grandpa doesn’t give up easily, and it turns into an all-out war between the two. Christopher Walken, Uma Thurman, Eugene Levy and Rob Riggle also star.
