Mama Mia!

Amanda Seyfried has left Jennifer’s Body behind and is moving on to Julianne Moore’s in the Studio Canal psychological thriller Chloe, a remake of the French film Nathalie. The 24-year-old actress plays a call-girl hired by Moore, 49, to seduce her husband and, consequently, report back on their kinky sexual escapades. Liam Neeson stars as Moore’s husband.

Seyfried—God bless her for not being prudish like Natalie Portman—goes nude for the part, showing off both her tit-tays and tush. She also gets freaky with a very milfy Moore in an emotionally intense lesbian scene.

Chloe is directed by Atom Egoyan and penned by Erin Cressida Wilson, writer of the outrageous and sexually-charged cult classic Secretary. Check out the followin trailer to get a sneak peek at a nude Seyfried:

Coincidentally, this is the film Liam Neeson was working on when his wife Natasha Richardson died after suffering a head injury while skiing in Quebec.

The 57-year-old Irish bastard is having an impressive run of roles opposite hot, young actresses willing to lose their clothes in indie fare. Prior to Chloe, Neeson starred as a creepy mortician out to torment a naked Christina Ricci in Agnieszka Wojtowicz-Vosloo’s After.Life.

Chloe is slated for release in early 2010. Sony Pictures Worldwide Acquisitions Group holds the North American rights.
