Laura Marano & Oakes Fegley Star In 'The War With Grandpa' Trailer - Watch!

Laura Marano and Oakes Fegley play brother and sister in the upcoming holiday movie The War With Grandpa!

Their character’s parents are played by Uma Thurman and Rob Riggle, and Robert De Niro is their grandfather.

Here’s a synopsis: Sixth-grader Peter (Fegley) is pretty much your average kid-he likes gaming, hanging with his friends and his beloved pair of Air Jordans. But when his recently widowed grandfather Ed (De Niro) moves in with Peter’s family, the boy is forced to give up his most prized possession of all, his bedroom.

Unwilling to let such an injustice stand, Peter devises a series of increasingly elaborate pranks to drive out the interloper, but Grandpa Ed won’t go without a fight. Soon, the friendly combatants are engaged in an all-out war with side-splitting consequences.

The War With Grandpa is based off of the book of the same by Robert Kimmel Smith.

Christopher Walken, Cheech Marin and Jane Seymour also star in the comedy, set to hit theaters on October 9th.
