The unexpected moment happened during an emotional scene in the second season

Kaley Cuoco has shared the surprising moment Sharon Stone physically slapped her during a scene in The Flight Attendant in an unscripted take. The incident occurred while promoting the show on Jimmy Kimmel Live! on Monday (18 April).

Sharon Stone plays Cassie Bowden’s (Cuoco’s character) mother in the hit thriller series. According to Cuoco, the slap happened during a highly emotional 10-minute scene in the second season.

Before filming, Stone reportedly asked Cuoco how she felt about being touched during the scene. Cuoco recalled replying, “whatever you want to do, you’re Sharon Stone.” Cuoco said that at the end of a pivotal moment in the scene, Stone delivered a line, grabbed her face and slapped her.

Describing the slap as “for real,” Cuoco added that her reaction to the unexpected moment was equally genuine. “Afterwards, Sharon came up to me and said, ‘Oh, my God, I love you, I didn’t mean to do that, it just seemed right for the scene.’” Despite the surprise, Cuoco said she was slapped by Stone two additional times in subsequent takes.

The second season of The Flight Attendant follows Cassie as she attempts to embrace sobriety after relocating from New York to LA while also juggling her covert role as a CIA operative.

The series returns to the UK on 26 May via Sky Max and streaming platform NOW.
