After this movie wrapped, Consultant Chef Marcus Wareing said that if he had to hire anyone from the leading actors and actresses, he would choose Sienna Miller for her culinary skills.
To prepare for his role, Bradley Cooper trained alongside Clare Smyth, Executive Chef of London's Restaurant Gordon Ramsay, which has three Michelin stars.
Bradley Cooper claimed that the actors and actresses performed their food prep scenes with all of the hazards of a real kitchen, including flaming stoves and sharp knives. Also, real chefs were cast as extras in the kitchen, putting pressure on the actors and actresses to keep up.
World renowned chefs Gordon Ramsay, Marco Pierre White, Marcus Wareing, and Clare Smyth provided inspiration for Cooper's Adam Jones, though Cooper most closely emulates Ramsay's characteristic kitchen rants.
