Gemma Arterton argued with a Hollywood director after they wanted her to film an unplanned sex scene.
The 38-year-old actress - who rose to fame as a Bond Girl in 2008's 'Quantum of Solace' - refused to shoot the scene in the unnamed project after initially agreeing to the movie because the moment was meant to simply be heard off-screen.
She told Radio Times magazine: "I remember being on a set once and the director said, 'You're going to s**g on the bed'.
"And I said, 'No, this scene was written for us to be off screen, so you just hear the noises. I'd never have accepted the role if it was going to be filmed.'
"He put pressure on us on the day. The other actor, God bless him, was mortified. There were very high-profile people there."
Gemma refused to do the scene, but insisted she "only" felt comfortable doing so because she had more experience in Hollywood.
She added: "I said, 'You can't do that, I'm flat out not doing it.
"'I don't care if you think I'm difficult', but I only felt like I could say that because I was older."
'The Critic' star admitted she would have found it tougher to say no when she was younger and fearful for repercussions.
She explained: "It would have been really hard [to say no] when I was younger. You might get the sack, or get a terrible reputation.
"It was before we had intimacy coordinators, who are the go-between now — it's a totally different landscape.
"Anything you're not comfortable with is not going to happen."
Although she previously had a steamy on-screen romp with 'Quantum of Solace' co-star Daniel Craig, Gemma noted that the idea of being nude on screen never "fulfilled" her as a performer.
She said: "When I started acting, there was a lot of nudity. You were just expected to do it. It didn't fulfil me, it wasn't fun. It didn't feel like I was flexing my acting muscles."
