The only documentaries that I’ve heard of are The Compleat Beatles and The Beatles Anthology. Which one of those is better? Is there any others that are better than those?
Those are the two best ones out there. If you were to own one, it definitely should be the Anthology, in my opinion. It’s very well done and there’s just so much more footage (rare clips, live performances, interviews, etc.), plus it’s narrated by the Beatles themselves. Don’t expect it to be especially revealing on the Beatles’ personal lives, but it does give lots of in depth information on the band’s history (especially the early years), and it really is the definitive Beatles documentary.
… However, the Compleat Beatles has some unique footage and interesting information that is not in the Anthology, and it’s very well-narrated and artistically done (if a bit dated). If you don’t want to sit through the entire 8-part anthology, I would recommend this one; it’s wonderfully complete and compact as it is. Unfortunately it’s only on VHS, though.
The Anthology is the best choice.
