Race for Your Life, Charlie Brown Reviews
Charles Schulz gets sole writing credit, and I have to wonder how free he allowed himself to stray from the core Peanuts universe of the strip. One peculiar gag has Snoopy taking his chopper on the open road with Charlie Brown and Woodstock, a la "Easy Rider." And of course you don't want to think too hard about a group of elementary school kids left to fend for themselves in the snow-covered wild for days. I'm not sure that would have been accepted in the daily comic strip.
What's really strange is this movie obviously inspired the college comedy "Up the Creek" seven years later, which has the same plot and very similar perils.
I understand the Peanuts movies got heavy airplay on 80's HBO, so future film writers were evidently watching.
