The boy Pascal's real name is Pascal, and he is the son of the director, Albert Lamorisse. Part of the joy of The Red Balloon is the sense that maybe, just maybe, this could really happen. Wonderful, wonderful film which won many awards when it came out in 1956.
This movie is an offering for Paris In July.
I watched it on Netflix Instant, but it is also available on YouTube. It is only about 35 minutes long. You'll never forget it.
