Actor/musician Common, who won an Oscar earlier this year for his song "Glory" from Selma, has finalized a deal to star in Warner Bros.' DC Comics adaptation Suicide Squad. While this will be his first role in a superhero movie, Common was previously attached to play Jon Stewart, a.k.a. Green Lantern in director George Miller's Justice League movie that never made it into production. Of course, it's possible that he could be playing Jon Stewart once again, since Warner Bros. is developing a Green Lantern Reboot set for release in the year 2020, and Suicide Squad could be our introduction to Jon Stewart.

Regardless of who he's playing, Common joins a cast that already includes Jared Leto (The Joker), Will Smith (Deadshot), Margot Robbie (Harley Quinn), Jai Courtney (Boomerang), Joel Kinnaman (Rick Flagg), Cara Delevingne (Enchantress), Viola Davis (Amanda Waller), Adewale Akinnuoye-Agbaje (Killer Shark) and Karen Fukuhara (Plastique). Other cast members whose roles have not been confirmed include Jay Hernandez, Adam Beach, Ike Barinholtz, Scott Eastwood and Ray Olubowale. There are also rumors that Batman v Superman: Dawn of Justice stars Ben Affleck (Batman) and Jesse Eisenberg (Lex Luthor) may reprise their roles for this superhero ensemble.

David Ayer is directing from his own screenplay, with production currently under way in Toronto. Aside from providing the Oscar-winning song for Selma, Common also had a supporting role in the drama. He most recently starred in Run All Night alongside Liam Neeson. The actor will start shooting Relativity's Hunter Killer this July with Gerard Butler.
