Back in February, James Gunn got some big reactions from the internet with a post on social media featuring him hanging out with Zack Snyder, and more recently, the two filmmakers joined forces for cameos in an episode of Rick And Morty that had them playing versions of themselves.

Zack Snyder gives James Gunn some unsolicited advice about his 'Superman' movie as the two cameo on 'Rick and Morty': 'He's the Man of Steel, not the Man of Conversation.'
