Suicide Squad trailer: Watch the leaked Comic Con footage featuring Will Smith and Jared Leto

No release date for an HD version has been announced yet

The San Diego Comic Con is over for another year and so the internet has once again been flooded by fan footage of trailers not yet officially available.

Three of this years' big ones were held back: X-Men: Apocalypse, Deadpool and, perhaps most excitingly, Suicide Squad.

After showing the latest Batman v Superman trailer, DC went one step further to show some footage from their upcoming supervillain movie featuring Margot Robbie’s Harley Quinn, Will Smith’s Deadshot and Jared Leto’s Joker.

The leaked footage has a very dark tone, and ends with Leto’s Joker starring into the camera, saying: “I’m just going to hurt you, really, really, bad.” Watch it before it gets taken down.

There’s been a lot of controversy over Leto playing the Joker in recent weeks, with many criticising his tattooed look in the sneak peak we were given earlier this year.

Suicide Squad will tell the story of a team of supervillains who take on dangerous black op missions for the government and has been filming over the last couple of weeks.

The super-villain movie also stars Viola Davis as Amanda Walker, Joel Kinnaman as Rick Flagg, Adewale Akinnuoye-Agbaje as Killer Croc, Scott Eastwood as Steve Trevor and Jai Courtney as Boomerang.

Warner Bros are set to release the movie August 2016, less than six months after the release of Batman V Superman: Dawn of Justice in March next year.

The film is part of Warner Bros plans to roll out ten superhero and supervillain epics based on DC Comics characters by 2020.
