Ominous: The trailer for upcoming flick Suicide Squad was released on Monday after a fan shot video of it leaked at Comic-Con over the weekend
Swing: Margot Robbie plays one of the baddies, Harley Quinn, as she is pictured with a bat
Perhaps the most exciting part of the ominous sneak peek came at the end as Jared Leto fully reveled himself in character as iconic baddie The Joker.
The 43-year-old Oscar winner looked almost unrecognisable with pasty white make-up and neon green hair as he looked like he was administer electric shock torture on a victim.
Before the trailer ends, in his most menacing voice the baddie says: 'I'm not going to kill you. I'm just going to hurt you really, really bad.'
Game plan: At the beginning of the clip Viola Davis could be seen in her role as government agent Amanda Waller, who suggest creating a task force of dangerous people who can do good
Where's Mistah J? Robbie, 25, could be seen for the first time in her role as fan-favourite villain Harley Quinn while performing acrobatic moves tied up to the top of her prison cell by a sheet
The clip begins with government agents talking over dinner including Amanda Waller, played by Viola Davis, who makes an interesting suggestion: 'I want to assemble a task force of the most dangerous people on the planet who I think could so some good.'
'And if anything goes wrong we blame them, we have built them deniability. Getting people to act against their own self interest is what I do for a living.'
It quickly transitions to inside of a high-security prison, giving the first look of 25-year-old Robbie in her role as fan-favourite baddie Harley Quinn.
The accomplice and girlfriend of Joker could be seen hung up by a white sheet in her jail cell while performing some acrobatic moves.
Puncher's chance: Will Smith is shown in his role as Floyd Lawton/ Deadshot hitting a punching bag in the jail
Not so glamourous: Model Cara Delevingne could be seen in dirty, murky water June Moone/ Enchantress
Moment of clarity: Deadshot seems to have an understanding of what their duties are as he stands next to Rick Flagg, played by Joel Kinnaman, and says: 'Let's go save the world!'
After that quick shots of the other prisoners/ future members of the Suicide Squad are shown including Floyd Lawton/ Deadshot (Smith) and June Moone/ Enchantress (Delevingne).
Deadshot seems to have figured out the idea as he explained: 'So that's it huh? We're the patsies. We're some kind of Suicide Squad. Let's go save the world!'
Seen for a short period of time was Batman, portrayed by Ben Affleck, who is shown momentarily while clutching onto the top of Joker's shiny pink Ferrari.
Sultry: Harley Quinn could be seen scantily clad in her favourite argyle print
Sadistic: The girlfriend/accomplice of the Joker licked a prison bar as she says 'you're in so much trouble'
Ride of her life: She could be seen with mouth agape as she rides in the passenger side of the Jokers ride
Caped crusader: Batman, played by Ben Affleck, could be seen atop the Joker's shiny pink Ferrari for a brief moment
Followers worldwide were able to see the clip earlier as expected as fan shot versions were leaked online during the film's Comic-Con presentation.
Warner Bro.'s marketing chief Sue Kroll addressed the leak in a statement: 'It’s unfortunate and ultimately damaging that one individual broke a long-standing trust we have enjoyed with our fans at the convention by posting early material, which, at this point, was not intended for a wider audience.'
Leto has quite big shoes to fill as Joker predecessors before him include Jack Nicholson, Mark Hamill and the late Heath Ledger.
Demented: The Joker could be seen toward the end of the video with two metal rods that looked they are used for electrical torture
Iconic: The clip ends with the Joker telling his victim: 'I'm not going to kill you. I'm just going to hurt you really, really bad'

The film also stars Jai Courtney, Scott Eastwood, Joel Kinnaman, Common, Adewale Akinnuoye-Agbaje, Jay Hernandez, Adam Beach and Ike Barinholtz.
