Rourke used Amy's Rehab to prepare for Iron Man 2

London (ANI): Mickey Rourke used his own favourite soundtracks to prepare for his role of Russian villain Whiplash in Iron Man 2. The Wrestler star used songs 'Rehab' by Amy Winehouse and 'Crazy' by Gnarls Barkley to get under the skin of his character, and wanted to use tracks of his own choice for his scenes.

In fact, the Hollywood actor went all the way and set up a giant sound system to play the tracks for his dramatic scenes in the movie. Jon Favreau, moviemaker, told the Entertainment Weekly, "Mickey has his process, man. He wants the music loud. We'd get these big speakers... and there were a handful of songs he would want played.

"In that scene when he's walking down the racetrack with the whips out and people are running and screaming and there's tyres on fire, Rehab was blasting." Iron Man Robert Downey, Jr., however, seemed unimpressed.

The Daily Express quoted him as saying, "I always thought, like, why is he coming at me with, 'They tried to make me go to rehab?' If I ever hear that Gnarls Barkley song again, it'll be too soon."
