The War With Grandpa is in Theaters October 9, 2020!  Peter is thrilled that 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.
