Depp is to star in the new movie - which shares a title with a 2004 film he starred in as 17th century poet John Wilmot, but is unrelated - opposite the 40-year-old French actress.

The project will be helmed by 'X-Men: The Last Stand' director Brett Ratner and the script has been penned by Ben Kopit.

In the movie, Depp will play a French diplomat who is accused of sexual assault and is subsequently put under house arrest.

Deadline reports the plot is based on the 2011 allegations made against French politician Dominique Strauss-Kahn, who had to resign from his position as the managing director of the International Monetary Fund after a New York hotel maid accused him of sexual abuse.

He was also placed under house arrest but the criminal case ultimately fell apart due to a lack of evidence. Kahn settled a civil suit out of court.

Now Depp is on board the title of the film - which is being touted to foreign buyers at the Cannes Film Festival - is likely to be changed.
