Anna Friel has confessed that stripping off on camera didn't feel like a big deal any more because there is so much more nudity on screen.
The actress plays Jean Raymond, the wife of porn baron Paul in new film The Look Of Love.
Jean was a choreographer for Raymond's strip shows and later posed for his magazine Men's Only. But Anna pointed out she has played roles where she has been filmed in the bath or the shower, so she was used to being naked in front of a camera.
She added: "For my part when I got to it, I was so used to it. It's not such a big deal, I think we've become a bit more relaxed now with our approach to nudity and nakedness."
The film follows Raymond's life from the 1950s when he started his revue shows in Soho, through the 60s, 70s and 80s.
Anna revealed: "Strangely enough I felt more liberated, not just because of the period of what the 70s mean to us, but in those outfits the shorter the skirts got and the longer the hair got.
"But in the 50s I felt much older even though I was only supposed to be playing 22, because everything was much more severe. I loved the very tight lines of the clothes and the elegance of it. But my personality and myself suit the 70s a little more. Or the swinging 60s!"
The Look Of Love is out on Friday April 26.
