"Suicide Squad" director David Ayer tweeted a photo last week of the cast of the DC comics supervillains movie that created a bit of a buzz online. The picture was taken during a table read and was the first to feature the actors together. There was Will Smith, Margot Robbie, Viola Davis and Cara Delevingne. (Jared Leto, who plays The Joker, was not on hand.) And then, all the way to the right side of the crowded photo, was a familiar but unexpected face: Ike Barinholtz.
