"Guardians of the Galaxy" director James Gunn had a lot to say on Twitter about people he will not work with: "I always do due diligence on actors & production heads with directors, actors, producers & crew members I trust. If it checks out they're jerks (not just cranky or curmudgeons but actual jerks) or irresponsible, I don't hire them. Some actors I already know never to even consider."
He added, "If it's their temperament & it's serious, I'll immediately recast. Life's too short for assholes. Same if they're repeatedly very late, which I hate, or unprepared. I have a long list of actors, A-list & otherwise, I'll never work with for these reasons…."
