Pictured from left to right are: Adam Beach (Cowboys & Aliens) as Slipknot, Jai Courtney (Terminator: Genisys) as Captain Boomerang, Cara Delevingne (Paper Towns) as Enchantress, Karen Fukuhara as Katana, Joel Kinnaman (RoboCop) as Rick Flagg, Margot Robbie (The Wolf Of Wall Street) as Harley Quinn, Will Smith (Men In Black) as Deadshot, Adewale Akinnuoye-Agbaje (Thor: The Dark World) as Killer Croc, and Jay Hernandez (Hostel) as El Diablo.
The only one missing is Jared Leto’s Joker. Hope we get to see him with the gang next time. Or at least with Harley.
