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.'

James Gunn, writer and director of the off-kilter "Guardians of the Galaxy" films, tussled with various ideas on how to deliver a new take on Superman to the big screen.

James Gunn is shutting down the assumption that “ Superman ” has to be a box office blockbuster. The writer/director, who is also the co-head of DC Studios alongside Peter Safran, told GQ that the franchise tentpole film does not carry as much pressure at the studio as critics believe.
