I've not heard of it. Is it in french, or english?
It's an English Language movie based on the French comic book series, with Luc Besson at the helm. I'd almost guarantee it'll be translated to French, and based on the general snubbing it's getting in the states, I'd bet it does better in the French box office. I'm not sure when the worldwide opening is, it opened in the US this weekend just past.
