James Gunn’s spent the past few weeks talking about why he agreed to do Superman, and he’s also taking time to address the awkward part: agreeing to do it at the apparent expense of Henry Cavill’s superhero comeback.

James Gunn is looking back on the "terrible" experience of telling Henry Cavill he was being replaced as Superman by David Corenswet.

Superman introduced several stars to the rebooted DCU, but many of them have already appeared in other comic book projects.

"How can someone not think it’s real? I don’t understand," said Gunn in an interview with Josh Horowitz on the Sad Happy Confused Podcast. "So, in the test screenings people were like ‘is it real?’ you know, AI, nobody trusts anything."

With over $250 million at the global box office in less than week, James Gunn’s “Superman” is widely considered a win for the new DC Universe that Gunn and Peter Safran are spearheading at DC Studios.
