Mickey Rourke insisted on his own soundtrack for scenes in IRON MAN 2 - because Amy Winehouse's Rehab and CRAZY by Gnarls Barkley helped him get into character as Russian villain WHIPLASH.
The Wrestler star had a huge sound system set up for his dramatic scenes - and blasted his favourite tunes at his co-stars.
Moviemaker Jon Favreau tells Entertainment Weekly magazine, "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. wasn't impressed with all the noise: "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."
