Hayley Atwell Reveals She Was 8 Months Pregnant Filming New ‘Mission: Impossible-The Final Reckoning’ Fight Scene

Hayley Atwell got candid about her time taping Mission: Impossible – The Final Reckoning, and revealed that she was eight and a half months pregnant while filming a pivotal fight scene.

In an interview on The Tonight Show Starring Jimmy Fallon that aired on Thursday, May 22, Atwell, 43, went into detail about her on-set experience when the late-night host asked if the audience should know anything before he rolled a clip of her performance.

Atwell said, “I’ve never said before, actually. This is a Fallon exclusive. But during this fight sequence, we came back to it a few times to add a few elements to it. And in this clip, I’m actually eight and a half months pregnant.”

Fallon, 50, jumped in with surprise, saying, “Are you serious?”

The actress elaborated, “I’m serious. Yes. And I have to say, I was taken such good care of. Everyone was so supportive and they were like, ‘Oh, you can sit down, and we’ll have a stunt double do it.’ And I was like, ‘No! I’ve worked too hard. Let me do it.’ So I did it, and here it is.”

Atwell has appeared in the Mission: Impossible franchise as IMF agent Grace since 2023. Mission: Impossible – The Final Reckoning is the long-running action franchise’s eighth and final installment.

Atwell quietly welcomed her first child with her partner Ned Wolfgang Kelly in 2024. Details of their relationship and her pregnancy remain under wraps, though the actress seemingly confirmed she married Kelly in a May 19 episode of LIVE with Kelly and Mark in which she referred to him as her husband.

Kelly and Atwell got engaged in 2023. “We had rented this Airbnb that had lots of shelves with porcelain ducks on them, so it was quite a surreal setup,” the actress recounted to the Daily Mail‘s Eden Confidential in 2023.

She then detailed the moment he proposed. “My fiancé was in his [underwear] in the kitchen, and there was an accordion playing outside our window — which was timed perfectly but not planned,” Atwell told the outlet.

Mission: Impossible – Final Reckoning is in theaters now.
