"Twilight" star Robert Pattinson has agreed to star in a new movie and, well, it might need a title change.

Variety reports Pattinson will appear in a big screen adaptation of Guy de Maupassant's novel "classic novel "Bel Ami."  The picture will be the feature debut of London stage director Declan Donnellan.  

Pattinson told the trade, "It's a totally amoral character" and described it as a change of pace from his role of Edward in "The Twilight Saga" series. 

Published in 1885, "Ami" is a morality tale centered on Georges Duroy (Pattinson), a man who rises to the top by manipulating a series of powerful and wealthy mistresses.  It's unclear whether this incarnation will be contemporary or true to the source material as a period piece.

Ironically, if you do a google search for "Bel Ami" you'll immediately discover that the  title has become famous in modern times for another type of seduction and production.  [Be wary "Twilight" fans, this is for over 18 only.]  Something for the producers to consider before moving forward with that title.

Pattinson is currently in Cannes promoting "The Twilight Saga: New Moon" and his upcoming romantic drama "Remember Me."  He's also set to film Madeline Stowe's directorial debut "Unbound Captives" and "The Twilight Saga: Eclipse" before the end of 2009.

Also of note, Pattinson also told The Hollywood Reporter he is "committed" to appear as Edward Cullen for a final time in a big screen adaptation of the fourth "Twilight" novel, "Breaking Dawn." However, no official announcement on that project has been made by either Summit Entertainment or author Stephanie Meyer.

The independently financed "Ami" expects to begin production in Paris next year, perhaps with a new title in the works.
