Peter is thrilled that his Grandpa is coming to live with his family. That is, until Grandpa moves into Peter's room, forcing him upstairs into the creepy attic. And though he loves his Grandpa, he wants his room back - so he has no choice but to declare war.
Unfortunately the movie The War with Grandpa is not yet available on Disney Plus.
