Will Smith, Tom Hardy and Jared Leto have been confirmed for upcoming DC Comics supervillain movie Suicide Squad.

Leto will follow the late Heath Ledger’s path and take on The Joker, while Smith will play Deadshot and Hardy the gang’s leader Rick Flag, Deadline reports.

Margot Robbie has already been cast as The Joker’s on-off lover and accomplice Harley Quinn, with Jai Courtney playing Boomerang and British supermodel Cara Delevingne set to star as Enchantress.

It has not yet been confirmed whether Jesse Eisenberg will reprise his Batman v Superman: Dawn of Justice role as villainous megalomaniac Lex Luthor in Suicide Squad, as reports have previously suggested.

The film’s storyline follows a group of villains who take on dangerous black op missions for the government in return for reduced jail sentences.
