I turn to this community seeking help looking for a film I saw around 2005/2006 in one of those small cable channels that used to pop up during a time and later dissapeared (at least in my cable company grid) and broadcasted non-english spoken movies mostly. It was about twin brothers, where one of them wants to take over his brother’s life as revenge. The interesting part is that the plan involves blackmailing him by revealing to his family that he was having an affair with another woman. Thing is that the woman is in fact a man using some kind of well elaborate disguise that allowed him/her to even have sex with the brother. The movie is French speaking. I don’t know the names of the actors as both times I catched it it was already about halfway through and never watched it untill the end. Any ideas?
Thanks in advance.
