James Ransone, the actor who played Ziggy Sobotka in the HBO series “The Wire,” has died.

And Ransone tells ET those scenes were "f**king hard" on the cast. "Jessica split her head open," he says, revealing that it happened while Chastain was filming in a "really tight space." In addition to Chastain, Ransone says "McAvoy hurt his knee and Hader pulled a groin muscle running around." They don't make stuff like that anymore, they don't make movies where you have big practical set pieces," he says.
