An unconfirmed report Tuesday evening from movie rumor site Latino Review states that Viola Davis has been cast in the key role of Amanda Waller in Warner Bros.' 2016 "Suicide Squad" film, according to unnamed sources. The article says the role is dependent on whether or not scheduling works out between Davis' commitments on ABC's "How to Get Away with Murder," in which she plays lead role Annalise Keating. Warner Bros. has not made an announcement on casting for the role.

Davis has been reported to be one of three front-runners for the role, along with Oprah Winfrey and Octavia Spencer. Thus far, Will Smith (Deadshot), Jared Leto (the Joker), Margot Robbie (Harley Quinn), Tom Hardy (Rick Flag), Jai Courtney (Captain Boomerang) and Cara Delevingne (Enchantress) have been officially announced for the film.

Amanda Waller is a key figure in most modern interpretations of the Suicide Squad, as the government agent in charge of the team of incarcerated supervillains executing high-risk operations in exchange for a reduced prison sentence. The character has been portrayed in live-action three times before: by Pam Grier in "Smallville," by Angela Bassett in the 2011 "Green Lantern" film and by Cynthia Addai-Robinson currently on CW series "Arrow."

Directed by David Ayer, the "Suicide Squad" film -- part of the shared continuity between DC Comics-based films that started with "Man of Steel" and continues with "Batman v Superman: Dawn of Justice" -- is expected for release on Aug. 5, 2016.
