Snyder said the photo marks the “homestretch” for filming Ben Affleck’s character in the new costume.
Warner Bros. unveiled the first trailer in July, premiering the footage for the superhero all-star movie at Comic-Con.
The upcoming film brings together DC Comics heroes Batman (Affleck), Superman (Henry Cavill), Wonder Woman (Gal Gadot), the Flash (Ezra Miller), Cyborg (Ray Fisher), and Aquaman (Jason Momoa).
Snyder began shooting “Justice League” in April from a script by Chris Terrio, with Amy Adams, Amber Heard, Jeremy Irons, J. K. Simmons, and Willem Dafoe also starring.
“Batman v Superman,” turned out to be mildly disappointing for Warner Bros., grossing $872.7 million worldwide on a $250 million budget. Snyder directed from Terrio’s script, which introduced Gadot as Wonder Woman, Momoa as Aquaman, and Miller as the Flash.
“Justice League” arrives in theaters on Nov. 17, 2017.
