Natalie Portman and Michelle Williams lending their claws for the sake of high art.

While Natalie Portman and Michelle Williams could likely command top dollar 4 an on-screen catfight, both of them are lending their claws for the sake of high art.

Natalie Portman and Michelle Williams, along w/ controversial film director Roman Polanski, have collaborated w/ Francesco Vezzoli, an Italian artist who specializes in faux advertising campaigns.

This time around, Vezzoli is making commentary on dramatic fragrance ads that feature stylized short films with A-list actors and directors (read: Nicole Kidman for Chanel, Charlize Theron for Dior.)

Natalie Portman and Michelle Williams star in "Greed," which tells the tale of a villainous blonde Williams coveting raven-haired Portman's precious bottled scent, resulting in romp on a hotel suite floor.

In stills released to DazedDigital.com, we can see the Academy Award-winning Polanski directing Michelle Williams on a stealth entrance and Natalie Portman on the perfect angle at which to rip out the Brokeback Mountain star's hair.

DazedDigital.com even offers a teaser trailer for the film, to be screened on February 6th at Rome's Gagosian Galler.

Reps for the gallery have been contacted to confirm that Natalie Portman and Michelle Williams and director will attend.
