"Don't make me punish you," Leto warned.
While we've seen lots of Suicide Squad set pics of Will Smith, Margot Robbie and more, there haven't been any of the Joker on the streets of Toronto.
It's probably safe to assume whatever footage they shot with Leto was inside the production studio, but that hasn't even been safe from prying eyes.
Leto is currently in Paris touring with his band Thirty Seconds To Mars.
"Suicide Squad" has an August 5, 2016 release date directed by David Ayer starring Will Smith as Deadshot, Jared Leto as the Joker, Margot Robbie as Harley Quinn, Cara Delevingne as Enchantress, Jai Courtney as Boomerang, Joel Kinnaman as Rick Flag, Viola Davis as Amanda Waller, Adam Beach as Slipknot, Karen Fukuhara as Katana, Adewale Akinnuoye-Agbaje as Killer Croc, Jay Hernandez as El Diablo, and Scott Eastwood in an unknown role.
