Jude Law gorged on cheeseburgers for his role in Dom Hemingway.

The British actor plays the titular role of a safe cracker who is released from prison in the new movie, and felt he should have more bulk in order to portray him properly.

He explained to website Access Hollywood: ''It just seemed clear that I needed to sort of look a little bit more excessive because he was someone who didn't eat healthily, probably had a bit more bulk, drank too much, smoked too much, so I certainly changed what I normally eat.

''[I had] Ice cream - couple of tubs of ice cream a day. Cheeseburgers were good. Lots of pasta, beer, milkshakes.''

Losing the weight again after filming was also no big deal for the usually skinny star, as he got tired of eating all of the calorific treats.

He added: ''I got kind of sick of it. It felt by the end like gorging. I don't really eat like that normally, so I just stopped.''

Jude has taken more stage roles than parts in movies in recent years, which he says is because he likes the energy rush he gets from being in theatre.

He previously said: ''Stage is just a different approach - like being on tour for a musician, as opposed to making an album. In the studio you have all these toys available to you, but when you're live, you have that adrenaline rush from knowing that at 7:30, you're on and you're off!''
