The starry two-minute clip sees Viola Davis' character Amanda Waller recruiting the criminal gang to help "save the world".
Margot Robbie's character Harley Quinn is given the most screen time, seen hanging upside down from her prison cell and later toting a baseball bat as a pretend gun, while Cara Delevingne's is shown having the accident that will transorm her into Enchantress. The big reveal of Jared Leto as the Joker is reserved for the end of the trailer when we see him torturing a hapless victim.
Prepare to see the green-haired villain and his shiny teeth in your nightmares tonight.
