CCG writes - "The War With Grandpa is a star studded comedy featuring Robert De Niro, Uma Therman, Rob Riggle, Cheech Marin, and Christopher Walken. The grandpa (Robert De Niro) is a widower who is struggling to get by since his wife passed away. Most technology eludes him like self-checkout registers at stores and smart phones. After a legal scuffle, he agrees to live with his daughter’s (Uma Therman) family though the transition won’t be easy for either of them. The grandson, Peter, is forced to give up his room and relocate to the attic where he shares living space with mice and bats. It goes without saying that Peter is not happy with his new accommodations."
