"That's gonna be great," he told E! News. When asked about the backlash against Affleck as Bruce Wayne, Gordon-Levitt replied, "Oh, but it's gonna be good. I think it's gonna be good."
"Ben provides an interesting counter-balance to Henry [Cavill]'s Superman," Snyder said. "He has the acting chops to create a layered portrayal of a man who is older and wiser than Clark Kent and bears the scars of a seasoned crime fighter, but retain the charm that the world sees in billionaire Bruce Wayne. I can't wait to work with him."
And surprisingly, the director of the rival Avengers franchise agrees with Gordon-Levitt and Snyder.
"Affleck'll crush it," Joss Whedon tweeted. "He's got the chops, he's got the chin — just needs the material. Affleck & Cavill toe to toe — I'm in."
Ironically, Paddy Power pegged Gordon-Levitt as the favorite to play Batman before Affleck's casting was announced. It is unclear if the Don Jon actor will reprise his role as Robin in the sequel, though Cosmic Book News reported that Affleck's BFF Matt Damon was being considered for that role.
Fans are likely more excited about the latest casting buzz surrounding the Man of Steel sequel. Cosmic Book News reported that Bryan Cranston of Breaking Bad fame has been cast as villain Lex Luthor for at least six Justice League films. This has not been confirmed, though the actor told Metro this month that he would be interested in the role.
"Give me a call," he said. "I like Lex Luthor. I think he's misunderstood. He's a loveable, sweet man."
While the Man of Steel sequel has not yet started filming, some fans have created their own fake trailers online.
Check out video of a fan-made trailer featuring Affleck, Cavill, Cranston and Amy Adams.
