20 Amazing Marvel Cinematic Universe Cameos You Never Noticed

James Gunn got lots of his friends to cameo in Guardians Of The Galaxy (keep an eye out for Mikaela Hoover as one of Nova Prime's assistants), but perhaps the hardest to spot - or should that be hear? - was Rob Zombie as the voice of the Ravager's Navigator. That's the ship piloted by Yondu, and after turning up in Slither and Super, it should really come as no big surprise that Gunn once again enlisted the musician and director for the Marvel movie.
