Primarily, it impacted Chastain’s physical involvement in terms of filming a few of the stunt scenes.
What exactly happened to Chastain on the set of “The 355”?
The actress opened up about all the scary details during her conversation with Corden and Cruz.

“I was doing a fight scene and it was on a marble floor.
I had fallen and hit my head.
I misjudged the distance.

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?
What is happening?'”
It ended up being a bruise that the stunt double pushed back into Chastain’s head.
We’re glad that Chastain is okay!
