No? Shame on you. It's 18 love stories, each one set in a different district in Paris, each directed by a different director and tons of actores and actrices. Just to name a few directors you have Gérard Depardieu, Olivier Assayas, Sylvain Chomet, Gus Van Sant or the Coen Brothers. When it comes to actors, well, they are literaly, tons: Gaspard Ulliel, Natalie Portman, Elijah Wood, Steve Buscemi, Maggie Gyllenhaal, Nick Nolte, Fanny Ardant, Emily Mortimor, and many more. (movie trailer here).
Well, now there is going to be an american version, this time focussing on NYC. The concept is the same - 1 director per area in NYC and a handfull of great actors and stories - and it is almost opening in the US. Can't wait to watch this one. (poster below, movie info here and trailer here)
