The Red Balloon
I remember watching this in my high school French class and decided to revist it. It's a cute, funny little short film about a bullied kid who finds a little light with a sentient red balloon that decides to follow him and give him the light he needs and wants. The movie is beautiful and the colors are so vivid. Its almost completely silent and does an excellent job at conveying story and themes without any words at all. Its just really good, and I recommend it for anyone! It's on YouTube and only just over 30 mins.
