Jared Leto and Will Smith are among the stars confirmed for 'Suicide Squad'.

The 'Dallas Buyers Club' actor and 'Men In Black' star are among the star-studded cast confirmed for the upcoming Warner Bros. supervillain movie based on the DC comic book of the same name, Variety reports.

Will Smith's 'Focus' co-star Margot Robbie, 'The Dark Knight Rises' actor Tom Hardy, Divergent's Jai Courteney and model-turned-actress Cara Delevingne will also star in the film to be directed by 'Fury' filmmaker David Ayer.

Warner Bros. president Greg Silverman said: ''The Warner Bros. roots are deep in this one. We look forward to seeing this terrific ensemble under David Ayer's amazing guidance, give new meaning to what it means to be a villain and what it means to be a hero.''

The script centres on a team of supervillains who are given a death-defying mission to complete in return for redemption from the government.

Although the names have long been rumoured for the highly anticipated project, it's now been confirmed which stars will be taking on which roles.

Leto will transform into The Joker - a character made famous by Jack Nicholson and the late Heath Ledger - while Smith will play Deadshot, Hardy Rick Flag, Robbie Harley Quinn, Courtney Boomerang and Delevingne Enchantress.

Jesse Eisenberg is also said to be in talks to play Lex Luthor in the upcoming project, a role he will first take on in 'Batman v Superman: Dawn of Justice'.

However, the studio is yet to cast the role of supervillain team leader Amanda Waller, although Viola Davis, Octavia Spencer and Oprah Winfrey are being eyed for the part.

'Suicide Squad' - which is scheduled to open in cinemas on August 5, 2016 - is expected to begin shooting in Toronto next April.
