I recently watched Paris, je t'aime, a wonderful movie that will get you laughing, crying, happy, sad, pensive, and wanting more.
What's interesting about this is movie is its format: it's comprised of 18 5-minute segments, each telling a different story, each directed by a different director, each using a different cast, each representing one of Paris' arrondissements. Initially, there were supposed to be 20 segments (because there are 20 arrondissements), but apparently 2 of the segments did not make it into the movie because they could not be integrated with the rest of the story.
The movie boasts an international cast, including Juliette Binoche, Steve Buscemi, Gerard Depardieu, Natalie Portman, Gena Rowlands, Elijah Wood and Nick Nolte, among others.
Some segments are more interesting than others, some touched me more than others, but this is still an excellent movie that I highly recommend you watch.
It was showing here during the International film festival a couple of months ago, and I'm sure it'll be out again sometime soon (it's set to open in the US in early 2007).
