Sienna Miller is set to co-star with Bradley Cooper in the Weinstein Co. pic “Chef.”

Omar Sy also stars, and John Wells directs the pic.

Steven Knight penned the script, the story of a chef who gathers a crew in an attempt to create the best restaurant ever.

Wells, Michael Shamberg, Stacey Sher and Erwin Stoff are producing.

The food industry has received recent attention in Hollywood. Jon Favreau, of course, bowed his own culinary-focused pic with the same name at this spring’s South by Southwest.

This project marks a reteam for Miller and Cooper, who just wrapped production on the Clint Eastwood pic “American Sniper.”

Miller is filming the Warner Bros. mob film “Black Mass,”which he will follow with the Ben Wheatley pic “High Rise.” Miller also has a handful of films set to bow later this year — including “Mississippi Grind” and “Foxcatcher,” which recently bowed at Cannes to rave reviews.

She is repped by WME, the Schiff Co. and United Agents.
