Task Force X is the Suicide Squad

DC's highly-anticipated take on the super-villains known as the Suicide Squad bows in 2016. Under the moniker Task Force X, the squad is a government-sanctioned group executing dangerous missions from a base in Belle Reve Prison. David Ayer (Training Day, End of Watch) will write and direct the summer blockbuster, which promises to be one of the darkest comic book films ever. (Photo: Twitter/@DavidAyerMovies)

The Joker is Back

Jared Leto (Dallas Buyers Club) will follow in the footsteps of Cesar Romero, Jack Nicholson and Heath Ledger to play the iconic character. Leto, who practiced method acting for the role, gave each cast member a gift from the Joker. Margot Robbie kept the live rat that was gifted to her because, “if Harley got something from Joker, she’d probably cherish it.” In the comics, the Clown Prince of Crime is not a member of the Suicide Squad.
