French actress
Emmanuelle Béart is probably best known to the general audience for starring opposite Tom Cruise in Mission: Impossible in 1996, which is to date her only big Hollywood movie.
She did make a big career in her home country though, winning a César Award for Best Supporting Actress once, and receiving several nominations for various other awards as well.
You can see her naked in like two dozen French movies, clips and caps from those are
available at Mr. Skin, La Belle Noiseuse being one of the best. She's naked throughout the entire four hours of the movie, posing naked as a model for a painter.
Here are some caps from the movie. And if interested, you can get the
clips at Mr. Skin.
La Belle Noiseuse is available on DVD.
