Main characters: Bear cubs. :)
Genre: I'm not actually sure...
Primary actors: None, just bears. Well, there are a few humans, but they aren't primary.
Length: About 50 minutes.
Based on: *ahem* I'm not actually sure if it's fiction or non-fiction. :P I'd say a little of both.
Time period: 1960's...hilarious to see the hair on the women, outfirts, and cars. ;)
Exciting events: Hmmm.
Year it came out: 1963
My overall opinion: It's fun. A kids' movie. Has some laughable parts. :)
