BERLIN -- Jennifer Aniston, Mark Duplass and Ben Kingsley have joined the cast of Convention, a science-themed comedy from commercials director Justin Reardon.

Duplass, onscreen in Oscar-nominated Zero Dark Thirty, stars as Paul, a mild-mannered inventor who, together with his feisty sister Abby (Aniston), sets out to change the world of box storage with a new, five-sided box.

Kingsley will play Bobby Schroedinger, a maniacal box magnate determined to foil their plans.

Christopher Painter (The Adventures of Jimmy Neutron: Boy Genius) penned the script to Convention, which Paul Schiff and Tai Duncan of Schiff Productions will produce. Reardon, who attracted attention with his Budweiser commercials, just wrapped production on his first feature, the comedy A Many Splintered Thing, which stars Chris Evans and Michelle Monaghan

Convention is a wildly original and funny screenplay,” said Schiff. “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.”

K5 International will handle international sales on the project and will be shilling Convention to buyers at the European Film Market in Berlin. CAA and ICM Partners co-represent the film for North America.
