“I was doing a fight scene and it was on a marble floor.

I had fallen and hit my head.

I heard a crack,” Chastain said (viaYahoo!).

“I hear a crack.

And I’m sitting there, I’m like, ‘Put what back in?

Are my brains outside of my face?

It ended up being a bruise that the stunt double pushed back into Chastain’s head.

We’re glad that Chastain is okay!
