Filming scenes outside, Cooper looked well put together in blue jeans and a black leather jacket over a tight black t-shirt. Miller, meanwhile, paired faded black jeans with a royal blue coat and matching knit hat. The two were shooting Adam Jones – about a chef of the same name – outside of a Burger King.

On Sunday, Cooper headed inside the Leicester Square Burger King to hone his burger flipping skills. “Bradley was training alongside genuine Burger King staff,” a sourced told The Sun. “The aim was to learn the art of the flip, which he nailed fairly quickly.”

In Adam Jones, Cooper plays the eponymous chef, who hopes to open up his own restaurant in London and earn a third Michelin star. Miller’s character Helene is already established as one of the city’s best chefs. Adam hopes to get her help and partnership to get his ambitious plans underway.

Adam Jones, previously titled The Chef, is being helmed by director John Wells. Fifty Shades of Grey’s Jamie Dornan, Uma Thurman, Daniel Bruhl, Emma Thompson and Alicia Vikander are also starring.
