"Bel Ami" tells the story of Georges Duroy, a soldier of the French army in Algeria who arrives in Paris broke and unwilling to work at all. Bel Ami (which is the nickname given to him by successive lovers) has not been blessed with the gift of intelligence or culture, but is physically attractive, so naturally captures the attention of all women that cross his path.

Of course, this is still unconfirmed.
UPDATED! Traced all possible sources, including IMDb... And there is still no US distributor committed to the film - so this is very unlikely. Once the movie gets a confirmed distributor - then we can be talking about some serious release dates.
UPDATED! Release date in Russia is claimed to be on February 24, 2011. source and source
