Jessica Chastain said she went to hospital after hitting her head on a marble floor shooting a stunt for 'The 355'

• Jessica Chastain said on "The Late Late Show with James Corden" that a stunt went wrong on "The 355" set.
• Chastain said she went to the hospital after hitting her head on a marble floor.
• She added that she continued filming until she was convinced by her co-stars to go to the hospital.

Jessica Chastain said on "The Late Late Show with James Corden" that she had to go to the hospital after she hit her head during a stunt on "The 355" set.

Chastain is the producer and star of the upcoming action movie about a group of spies from different international organizations that team up to save the world. Simon Kinberg, the director of the movie, told Insider that Chastain had asked to do a lot of the stunts for the movie herself rather than get a stunt double to do it.

During the appearance on "Corden" to promote "The 355," Chastain revealed that she had to go to the hospital after hitting her head on a marble floor whilst filming a fight scene for the movie. Chastain said that she had to fall and hit her head on purpose but had misjudged the distance.

"I heard a crack," Chastain recalled. "Yeah, that may be why I am the way I am today. I heard a crack. Everyone stopped and looked scared and I was a bit stunned like 'I don't know what's happening.' My stunt double comes up to me. She was so sweet. She is French and doesn't speak a lot of English. And she comes up to me and goes, 'I'm sorry but I have to put it back in.' And I'm sitting there like 'put what back in? Are my brains outside of my face? What's happening?'

"And I guess it was just a bruise she was pushing back in my head. I did a couple more takes because I don't give up easy, and then I went to the hospital."

Chastain's co-star Penélope Cruz, who was also part of the interview, added: "Because we convinced you to go to the hospital because she didn't want to go. She wanted to keep going. I was like: 'You're going to the hospital.'"

Cruz later said she was "so relieved" that she didn't have to do as many stunts as her co-stars.

In one of the featurette trailers for "The 355," it was revealed that Chastain herself did the stunt where her character Mace jumps from a dock beam onto a metal container on a boat. Kinberg told Insider that this particular stunt was "terrifying to watch."

He said: "In fact, I couldn't watch her walking along that beam because it was basically like doing a tight rope walk 50 feet above the above a wooden dock in heels. The docks were the ones where I really felt like she could die."

"Every time she was like, 'Oh, I can do that fight. I'm gonna learn it in two days.' I was like, 'Or you could just let the stunt woman do it. Nobody will know the difference.' And she said, 'They'll know the difference and I'll know the difference.'"

"The 355" is out in theatres this Friday. Lupita Nyong'o, Diane Kruger, Fan Bingbing, and Sebastian Stan also star in the spy action movie.
