Recent photos snapped from the set of Zack Snyder's superhero reboot show Cavill's Superman in full costume, without his red trunks, as he approaches villains General Zod (Michael Shannon) and Faora (Antje Traue).
The images surfaced on an unofficial Superman: Man of Steel Facebook page alongside pictures of a school bus and a damaged aircraft to be used in Smallville scenes.
Both Christopher Reeve and Brandon Routh's Superman movies carried over the character's red underpants from the comic book.
Cavill's Superman outfit was revealed earlier this month, but deliberately cast in shadow to keep fans guessing about his superhero attire.
The Christopher Nolan-produced movie's costume will tie in with the Man of Steel's new outfit in DC Comics' forthcoming 'New 52' relaunch.
Man of Steel, co-starring Amy Adams, Russell Crowe, Kevin Costner, Diane Lane and Laurence Fishburne, will open in cinemas on June 14, 2013.
