DC Studios CEO James Gunn and fellow filmmaker Zack Snyder made surprise appearances on this week’s episode of “Rick and Morty,” lending their voices to guest star as over-the-top versions of themselves.

“They were good sports,” said “Rick and Morty” exec producer Scott Marder. “Both of those guys sort of implied that this is the show they watch when they have downtime. So they were thrilled to get to be a part of the world, and there was no pushback or bristling. If anything, they laughed at anything we threw at them. There were probably, frankly, even more digs and more silly things we could have used. All they did was laugh it off.”
