Florence Pugh has revealed a camera "broke" when she was filming her Oppenheimer sex scene with Cillian Murphy.
The 28-year-old actress — who played Jean Tatlock in Christopher Nolan's box office sensation — admitted it was "not ideal timing" for equipment to malfunction while shooting on a closed set because there were no alternative cameras available.
Speaking at an Oppenheimer panel discussion moderated by Jamie Dornan, she said: "In the middle of our sex scene, the camera broke. No one knows this, but it did.
"Our camera broke when we were both naked, and it was not ideal timing."
Wrapping her arm around herself, she said: "Cillian and I are in this room together. It's a closed set, so we're both holding our bodies like this."
But the actress decided to use the malfunction as an opportunity to learn more about the technical aspects of making a movie.
She said: "I'm like, well, this is my moment to learn. [I asked the man who came in to fix it] 'So tell me, what's wrong with this camera?'
"You just make your moments. I'm like, 'What's going on with the shutter here, buddy?'"
The director explained there was an issue with the way the light was coming in.
Florence added: "It was just crazy that every person on this set was so knowledgeable and was so ready to make this kind of a movie that there was no dull moment. It was all amazing. It felt like we were lucky to be there every second of the day."
Florence recently told of how Christopher was apologetic when he offered her the role of Jean because it "wasn't a very big role", but that didn't matter to her.
She told MTV UK: "I didn't really know what was going on or what it was that was being made.
"Except I knew that Chris really, really wanted me to know that it wasn't a very big role, and he understands if I don't want to come near it. And I was like, 'Doesn't matter. Even if I'm a coffee maker at a cafe in the back of the room, let's do it.'"
