It's confirmed that Suicide Squad has a post-credit sene (actually mid-credit-ish).
No spoilers, but users on Twitter and social networks who got to see Suicide Squad early confirm the existence of a Suicide Squad post-credit scene, which I believe marks the first post-credit scene in a DC movie since Green Lantern (Mark Strong's Sinestro).
You don't have to wait until all the credits are over, either, as there is no final post-credit Suicide Squad scene at the end.
Update: Director David Ayer confirms a Suicide Squad post-credit scene in the below video: "Just leave the theater very slowly."
Hopefully the Suicide Squad post-credit scene means more are to come as Marvel always does a good job with their own post-credit scenes. Now that the Justice League universe is set in stone, maybe Zack Snyder and the other DCEU directors will add post-credit scenes as well.
Here is a bit of a teaser from a Twitter user on the Suicide Squad post-credit scene:
The post credit scene guys-it'll totally have you questioning the direction but it was well done! #SuicideSquad— Erika Fernandez (@CurlsAndSports) July 29, 2016
"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.
It feels good to be bad… Assemble a team of the world’s most dangerous, incarcerated Supervillains, provide them with the most powerful arsenal at the government’s disposal, and send them off on a mission to defeat an enigmatic, insuperable entity. U.S. intelligence officer Amanda Waller has determined only a secretly convened group of disparate, despicable individuals with next to nothing to lose will do. However, once they realize they weren’t picked to succeed but chosen for their patent culpability when they inevitably fail, will the Suicide Squad resolve to die trying, or decide it’s every man for himself?
