Rage Against The Machine guitarist Tom Morello has revealed that he is working on the score for upcoming movie, Iron Man 2.

Morello confirmed his participation on Twitter, although it is unclear how involved the guitarist is with the project.

“Is that really me in Iron Man? Of course. Iron Man kicks my ass,” he wrote.

“I'm working on score for Iron Man 2. Rockin. Movie is awesome.”

Meanwhile, the accompanying soundtrack for the Jon Favreau-direction movie, which has been compiled by AC/DC, is due out next month.

Iron Man 2 arrives in cinemas in the UK on April 30 and in the US on May 7.
