A Superman is born!

Warner Bros. has released the first photo of Henry Cavill in the new Superman reboot: Man of Steel.

Cavill has been on a crazy workout plan and eating 5,000 calories a day to bulk up for the role -- we can tell!

Christopher Nolan, who did the Batman movies, is writing and producing -- so this should be good!

Amy Adams, Laurence Fishburne, Diane Lane, Kevin Costner, Michael Shannon, Julia Ormond and a famous Aussie star in the pic ... see who it is after the jump!
