This is a mediocre movie from a brilliant book. The script writers did everything they could to slaughter it, making it into a cutesy children's movie. Not to be outdone, the casting department then finished pulling everything apart, leaving it to the actors to attempt a salvage. Roddy McDowall turned in a good performance as always; there was just something about his English accent that seemed out of place on the Wyoming plane.I voted a six, because it's a fair movie if you forget that it's supposed to be from the book, which apparently nobody in the crew read.
