Christopher Walken and Robert De Niro are set to appear in comedy The War With Grandpa alongside Eugene Levy.
The War With Grandpa, based on the book by Robert Kimmel Smith, is about a kid who reluctantly gives up his bedroom to accommodate his grandfather (De Niro), whom he loves but wants out of his room. The boy engages in a series of pranks meant to drive his grandpa out, but the old man is pretty wise to it and returns the volleys. De Niro and Walken play best friends in the film — as they did Deer Hunter, won the Best Picture Oscar and earned a Supporting Actor statuette for Walken.
The film is set for release on April 21, 2016.
