David Ayer teased very few details from the highly anticipated movie.
"Time for a movie about bad guys! DC has the best villains. It's all about bad versus evil," Ayer said, seemingly taking a jab at rival Marvel Comics.
"We were shooting last night in Toronto but we had to come down because you guys run this shit!" he continued.
Lucky fans inside Hall H were treated to the very first look at the film.
Leto and Robbie were clearly the stand-outs, with both nailing their characters' difficult voices. The former's delivery of the line "I'm not going to kill you, I'm just going to hurt you really, really bad" is guaranteed to send chills down your spine. Then there is Harley Quinn in prison, with Robbie hanging from the bars of a free standing metal cage using strips of fabric before the trailer cuts to her popping bubblegum. No sign of the words "Puddin'" or "Mr J", but it's a safe bet they will crop up in the movie.
The overall tone of the footage is certainly what you would expect from both the comic book run and the director of End Of Watch (2012) – dark and gritty with an emphasis on the 'reality'. Will Smith's (I Am Legend) Deadshot seems to be the leader of the ragtag team, but with these guys, nothing is guaranteed.
Smith, still sporting his characters shaved head and beard, told the crowd, "We are banging out something that is absolutely fantastic. We'll see y'all next year!"
The complete cast list includes Will Smith as Deadshot, Jared Leto as The Joker, Margot Robbie as Harley Quinn, Joel Kinnaman (RoboCop) as Rick Flag, Jai Courtney (Jack Reacher) as Captain Boomerang, Cara Delevingne (Anna Karenina) as Enchantress, Viola Davis (Prisoners) as the government agent who puts the team together, Amanda Waller, Adewale Akinnuoye-Agbaje (Thor: The Dark World) as Killer Croc, Karen Fukuhara as Katana, Adam Beach (Flags Of Our Fathers) as Slipknot, Jay Hernandez (Hostel) as El Diablo.
Many of the actors listed were in the room to say hello to the fans, but there was no actual question and answer session for the audience, which might have upset everyone if it weren't for the quick cut to the Batman V Superman: Dawn Of Justice footage.
The Warner Bro panel also featured a concept art showreel that blew away the assembled audience with a list of all the planned DC titles on the way. Including Wonder Woman, Justice League 1, Justice League 2, The Flash, Aquaman, Cyborg and Green Lantern Corps.
That's right, the Green Lantern movie will concentrate on the fictional intergalactic military police force, and not the solo Lantern you might remember from the unfortunate Ryan Reynolds outing in 2011. The art shown was cut together with action shots of the Suicide Squad walking together, The Right Stuff (1983) style, screened across three walls of the vast Hall H.
Suicide Squad, as you may know by now, brings to life the comic book adventures of a group of DC Comics villains and anti-heroes coerced by shadowy government forces into completing hazardous missions with the lure of pardons or reduced punishments. Ayer is taking aim an 5 August 2016 release date and his film will be the first of the new DC Entertainment titles to follow Zack Synder's (Man Of Steel) Batman V Superman: Dawn Of Justice.
