Uma Thurman and Rob Riggle have signed on to star alongside Christopher Walken and Robert De Niro in The War with Grandpa, director Tim Hill’s adaptation of Robert Kimmel Smith’s 1984 children’s book.
The official book description for The War with Grandpa reads: “Peter is thrilled that Grandpa is coming to live with his family. That is, until Grandpa moves right into Peter’s room, forcing him upstairs. Peter loves his grandpa but wants his room back. 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. They used to be such great pals. Has their war gone too far?”
The War with Grandpa is being co-financed by Emmett/Furla/Oasis and Marro Films, and was initially brought to Marro Films CEO Rosa Morris-Peart by her then 8-year old son Marvin III, who read the book at school and felt it would make a great movie. Now aged 11, he will receive an executive producer credit on the film.
