Well, for an American director, to come in France, at the most prestigious French film festival, to present a movie about a French mythical symbol... played by a Hollywood actress... I'll just say Coppola does have balls.
Don't get me wrong, she is very respected here (her two first movies got rare reviews in the french press), but we are SOOOO protective and snootty about our historic heritage. The fact that it is an American (even worst, Hollywood) production was controversial from the start in here. Alain Delon refused to play Louis XV because it was an American production (the same man plays in French bad TV series without problem).
Typically French reaction.
Just curious if the audience was only made of French viewers or if it was a mix of international critics. That could make a huge difference.
