The Red Balloon, originally released in 1956, by French filmmaker Albert Lamorisse, won an Oscar for Best Original Screenplay. A 34 minute short, filmed in the Ménilmontant neighborhood of Paris. The film received a 95% rating on RottenTomatoes. And, although it's been mentioned in comments once or twice here at MetaFilter, I don't believe it's ever been linked. Find your favorite 6 year old kid, make some popcorn, open a bottle of wine, champagne might be best, sit back, and enjoy. You'll find it a fantastic conversation starter with your little one.
