Nicole Kidman, Hugh Bonneville and Julie Walters can be seen at Daventry Country Park on Saturday, July 25.
The trio appear alongside Jim Broadbent and Peter Capaldi in the Paddington movie, one of two films to be shown at the at the Daventry Family Cinema event.
The other is the animated hit The Boxtrolls and the story of Eggs, a human boy raised by trash-collecting trolls, as he attempts to save them from Archibald Snatcher, a pest exterminator.
There are two chances to see both films with Paddington to be shown at 11.30am followed by The Boxtrolls at 1.15pm. The second round of the screenings starts with Paddington at 4pm with The Boxtrolls at 5.15pm.
People will be given coloured wrist bands on arrival, allowing them free entry to their chosen session only, to give as many people as possible an opportunity to enjoy the films. The screenings will also benefit this year from an improved sound system.
A number of paid-for children’s activities will also be taking place during the day, including face painting, a bungee run and a bouncy castle.
Entrance to the event is free. DACT buses are running from 10.30am starting at Lodge Road by the entrance to the leisure centre and going to the Country Park.
