A curious blue balloon leads a girl on an adventure through the streets of Paris, but when she crosses paths with a little boy and his red balloon, it becomes clear there's a greater magical force at work. The 1956 classic French film Le Ballon Rouge has a single scene with a girl and a blue balloon. Le Ballon Bleu tells her side of the story and serves as a prequel and a continuation to that classic children's film. Like the film it celebrates, this is a story about the magic and innocence of childhood and the importance of friendship. The film showcases many of the same Parisian locations as the 1956 classic French film to connect the two stories visually. The filmmakers designed the film so that it could be intercut seamlessly with the original. - IMDb
