Los Angeles: `The Americans` star Matthew Rhys has joined the cast of Bradley Cooper`s culinary movie.
The 39-year-old actor will play a rival chef who gets in Cooper`s way when he sets out to obtain a Michelin three-star rating, reportedly.
The film was recently given its third title - Untitled John Wells Project - until another name can be decided upon.
Cooper and co-star Sienna Miller have been photographed filming in London in recent weeks, including scenes at the Burger King restaurant in Leicester Square.
The Weinstein Co-produced project will also star Daniel Bruhl, Emma Thompson, Uma Thurman, Lily James, Jamie Dornan, Riccardo Scamarcio and Sarah Greene.
John Wells is on board as director, while Stacy Sher, Michael Shamberg and Erwin Stoff are producing.
