Oscar nominee Viola Davis has been cast as Amanda Waller, the no-nonsense woman in charge of the titular team, according to Latino-Review While not official, Davis is reportedly close to signing on just as soon as matters are sorted concerning her busy TV schedule with How to Get Away With Murder, the show she is currently headlining. Her previous movie roles include The Help, Doubt, and Ender's Game.Directed by David Ayer, the rest of the Suicide Squad movie cast includes Will Smith as Deadshot, Jared Leto as Joker, Margot Robbie as Harley Quinn, Tom Hardy as Rick Flag, Jai Courtney as Captain Boomerang, and Cara Delevingne as Enchantress. Waller, also known as "The Wall," is a hard-ass government agent who offers supervillains a chance to earn their freedom by going on secret missions that have a good chance of getting them killed.Unfortunately for Oprah Winfrey fans, if Davis does sign on the dotted line, then all hopes are dashed for her taking on the role. Winfrey, along with Octavia Spencer, were also rumored to be in consideration for Waller.For more on 2016's Suicide Squad and the casting of Viola Davis as Amanda Waller, stay turned to IGN.
