Uma Thurman, Robert Pattinson in Steamy New Film

Uma Thurman is set to help Robert Pattinson cut his teeth as a bad-boy journalist in Bel Ami, which begins filming next month.

"They are planning on doing the film Bel Ami in London," Thurman's rep tells PEOPLE, confirming the actress' involvement. Of a reported scripted kiss between the stars, he says, "The plot of the movie is not being released just yet."

Pattinson – cast in May in the story based on the 19th-century novel by Guy De Maupassant – will also be joined onscreen by Christina Ricci, reportedly as a promiscuous young housewife, and Kristin Scott Thomas.
