Bradley Cooper takes his career very seriously.
The 36-year-old "Hangover" actor worked a shift at a London's Burger King over the weekend to prepare for his upcoming cooking comedy, "Adam Jones," according to a report from the Daily Mirror. Cooper reportedly wanted to learn the ropes of working at a fast food restaurant chain to help him get into character.
"Bradley was training alongside genuine Burger King staff," a source told The Sun newspaper, according to the U.K.'s Daily Mirror. "The aim was to learn the 'art of the flip' which he nailed fairly quickly. There was no real fanfare from him. You'd never know he was a big star by the way he spoke to people."
The source added: "There was no real fanfare from him. You'd never know he was a big star by the way he spoke to people. He spent Sunday night learning the skills while the restaurant was open to the public and then filmed for most of the day on Monday."
Cooper, who is a two-time Oscar nominated actor, was reportedly a natural at the grill. In the film, which will be directed by John Wells, the actor plays a chef training to get a third Michelin star, Deadline.com reported.
The comedy also stars Uma Thurman, Emma Thompson, Daniel Bruhl, Riccardo Scamarcio, Lily James, Alicia Vikander, and "Fifty Shades of Grey" actor Jamie Dornan. The movie also reunites Cooper and actress Sienna Miller - both of whom recently wrapped the Clint Eastwood-directed film "American Sniper", due out in 2015.
The "Silver Linings" star also received some advice from celebrity chef Gordon Ramsay on how to improve his culinary skills.
"As well as giving Bradley a few top tips on cooking, I've taught him the most important thing he needs to know in order to get by in a kitchen - how to swear," Ramsay said.
