Welsh actor Matthew Rhys is set to test his culinary skills onscreen after joining the cast of Bradley Cooper's new chef movie.

The Hangover star Cooper will portray an embattled chef hoping to make his career comeback by landing his third Michelin star and Rhys will turn up the heat with the Oscar nominee as his movie nemesis, reports Deadline.com.

The currently-untitled film, co-starring Sienna Miller and Jamie Dornan, is currently shooting in London.

It is not yet known if The Americans actor will undergo any professional kitchen training before stepping foot onset, but Cooper received tips from celebrity chef Gordon Ramsay and even tried his hand at flipping burgers at a London branch of fast food chain Burger King last month (Jul14) in preparation for his role.
