I loved this documentary
If you really want the real inside story, you've GOT to watch this.

I only ever saw it once with my sons when they were kids so I would describe myself as the most casual of fans.
I still found this a fun watch. I just commented over on the Justin Long forum about how good an impressionist he was after watching his bits in this documentary.
I was surprised to learn that a TV series was in early development til the death of Alan Rickman put an end to it.
Also, I don't think Sigourney Weaver ever looked as hot as she did in this movie.
