This documentary pretty much covers most everything you wanted to know about the Making of Disney's classic 1954 20,000 Leagues Under the Sea.
This is exceptionally well done and culls footage from practically all the people involved, sometimes using archival footage where needed. The only downside is it pretty much renders the commentary also provided on said DVD useless as most all of the same information is covered and in fact is perhaps even more detailed in the documentary. Still it's very cool to put faces to the people who worked so hard behind the scenes on making this classic. A very thorough job covering its subject matter as all good documentaries should do.
