Directed by Tim Hill, The War With Granpa follows Peter, played by Oakes Fegely, who is thrilled that Grandpa is coming to live with his family. 

That is, until Grandpa, played by Robert De Niro, 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. 

With the help of his friends, Peter devises outrageous plans to make Grandpa surrender the room. But Grandpa is tougher than he looks. Rather than give in, Grandpa plans to get even.

Based on a book by Robert Kimmell Smith, the film looks like a lot of fun with a stellar cast that includes Uma Thurman, Christopher Walken, Jane Seymour, Cheech Martin, and Robert Riggle.  

Enjoy these movie clips because they are a lot of fun and good laughs. There is some great talent in this film. Walken looks like he is in his element with skateboarding and falling from the sky as Santa Claus.
