13 Best Secret Cameos In Marvel Movies

7. Tom Morello - Iron Man

The MCU has a bit of a thing for casting musicians in obscure roles: James Gunn has brought in Rob Zombie twice and intended to cast David Bowie in Guardians Of The Galaxy Vol 2 before his sad death. But it was Jon Favreau who cast the first rock star in the franchise.

He turned to Rage Against The Machine and Audioslave guitarist Tom Morello to play a Ten Rings terrorist in both Iron Man and the sequel as well as appearing on the soundtracks for both movies.
