Check out Suicide Squad set video out of Toronto featuring Will Smith, Margot Robbie, Adewale Akinnuoye-Agbaje, Jay Hernandez and Joel Kinnaman.
Kinnaman's Rick Flag apparently has some sort of grappling gun as we see him point in air and then fly up. We also see him (or a stuntman) dangling in the air.
We also see a behind shot of Harley Quinn where it looks as if her jacket reads "Propery of Joker."
"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.
