I've got it on tape, but for the longest time 'The African Queen', with Humphrey Bogart was not available at all. There still hasn't been an American release of it, even though this is such a classic film. I think this is/was because of rights issues.
Now it's available in the US & Canada (Region 1) as an import (whether it's a legitimate release is questionable). For a review of this version, check out: link
