Jennifer Aniston is set to add another comedy to her belt after landing a role in Convention.
The trio now appear to have signed on the dotted line, having previously been reported to have been interested in roles in director Justin Reardon's movie.
Jen, who has appeared in comedies such as Wanderlust, Horrible Bosses and The Bounty Hunter, will play a woman who sets out to change the world of box storage along with her inventor brother (Mark).
Sir Ben will play "a maniacal box magnate determined to foil their plans".
The movie will be produced by Paul Schiff and Tai Duncan of Schiff Productions.
Paul said: "Convention is a wildly original and funny screenplay.
"Justin Reardon's approach to the material is bold, inventive and bursting with imagination. We could not be more thrilled to have such a gifted group of actors on board to bring this film to life."
