Guardians Of The Galaxy Vol. 2: 30 Behind The Scenes Shots You Must See

7. Rob Zombie Cameo

At this point, James Gunn has made a game out of all the ridiculous cameos that are lined up for the movie, and he recently added another to the pile by bringing horror filmmaker and rock icon Rob Zombie in to record a voice cameo.

Zombie was only added to the movie back in late February, so it's safe to say that his role is going to be tiny even for the standards of a cameo, but considering that Gunn likes to include Zombie in just about every movie he makes, it's got to be done.
