'Twilight' star Robert Pattinson has revealed he found his sex scenes with Uma Thurman in new movie 'Bel Ami' 'disturbing' because her character uses sex as a 'weapon'.

The actor gets steamy with the screen beauty in the film in which he plays Parisian journalist Georges Duroy, but insists it was far from erotic because of the movie's plot, reports gossipblender.com.

'The sex scenes with Uma are kind of disturbing. Her character Madeleine kind of uses sex as a sort of weapon and my character thinks like an animal. There are a lot of sex scenes in this film, so I'm asking quite a lot of myself, and with lots of different people as well,' he said.

The movie is a big screen adaptation of French author Guy de Maupassant's 19th Century novel 'Bel Ami' in which an ambitious young Duroy sleeps his way to the top.

Film fans may also see Pattinson get steamy with Christina Ricci and Kristin Scott Thomas, who also star in the movie.
