Irish actor Sam Keeley has signed on for a supporting role in The Weinstein Company's Chef, joining Bradley Cooper, Omar Sy and Sienna Miller. It remains to be seen whether or not the studio will change the title, following the release of director Jon Favreau's indie comedy Chef.

The plot centers on Adam Jones (Bradley Cooper), a Paris chef who throws his career away because of his hard-partying lifestyle. After the talented chef sobers up, he assembles a crew to put together the best restaurant in the world, one that will earn him the rare and highly-coveted three-star Michelin rating. Sam Keeley is playing David, a chef recruited by Adam for his new restaurant, who ends up taking in his new boss when he needs a new place to live. Omar Sy and Sienna Miller are also confirmed to star.

John Wells (August: Osage County) is directing from a script by Steven Knight (Locke), with Stacey Sher, Erwin Stoff and Michael Shamberg producing. Shooting is expected to begin in the very near future.
