This 1977 animated film completely blew my little elementary school mind when I finally caught on the then nascent cable television during the early 80′s. I finally read the novel it was based on last year and the film is pretty faithful to the original vision. The film holds up ok all these years later. My favorite scene: The dog food can at the bottom of the pond… “the last visible dog”. This is an hour and 17 minutes long, just to let you know.
