The War with Grandpa (2020)

Peter is a young boy who feels invaded when he must move out of his room because his grandfather, Ed, is moving into his house after the death of his wife and Peter's grandmother. Determined to regain his space, his grandson devises a series of pranks that unleashes a war between the two, as Ed refuses to leave, causing a family chaos. A comedy based on a children's book that is reminiscent of others from the 80's or 90's and is entertaining thanks to a cast that includes Robert De Niro, Uma Thurman and Christopher Walken.
