Iron Man 2 was already going to be a pretty metal-friendly block buster. First, Marvel Studios announced the Iron Man 2: AC/DC soundtrack. Then it was revealed that Lamb Of God will contribute a new song to Iron Man 2: The Video Game. Now it has been confirmed who will help contribute to the rest of the movie’s soundtrack: Tom Morello.

While AC/DC’s hits will be featured throughout Marvel Studio’s big summer flick, the Rage Against The Machine guitarist has been working with composer John Debney on the film’s additional score. “…Iron Man kicks my ass. I’m working on score for Iron Man 2. Rockin. Movie is awesome,” Morello confirmed via his Twitter page. The trailer for Iron Man 2 made the film look cool enough as it is. But now that Iron Man and The Wrestler (Mickey Rourke plays the villain) will be duking it out to the sounds of Morello, the movie will sound even better!

In addition to playing guitar on the first Iron Man score, Morello actually made a cameo in the film. Remember the scene in the cave where the first incarnation of Iron Man is killing terrorists? Morello played terrorist #87 (or what ever they called the first terrorist who got his ass kicked by Tony Stark). Morello has also performed on the soundtracks to Spider-Man, Talladega Nights: The Ballad of Ricky Bobby and Dodgeball: A True Underdog Story. Iron Man 2  hits theaters on May 7.
