Some directors are known for working with the same actors multiple times, and "Superman" writer/director James Gunn is definitely one of those filmmakers. So it should come as little surprise that at least three "Guardians of the Galaxy" actors make cameos in the upcoming "Superman".

The James Gunn-helmed Phase 1 of the DC Cinematic Universe is upon us, beginning with Gunn’s upcoming Superman film — and as it turns out, the filmmaker and studio head considers the project to be absolutely crucial to making the Gods and Monsters phase work as an overall storytelling experience.
