Documentaries

I've been watching a lot of documentaries recently on famous people from various fields.  This has included David Bowie, Bruce McLaren, Garry Shandling and, most recently this weekend, Elvis Presley.  The documentary was kind of interesting for someone like me who didn't know much of the history of Elvis, particularly the early years, but I don't think it was particularly insightful and I'm sure there was nothing new to the Elvis aficionado.  However, I think a documentary on "Colonel Tom Parker' would be a LOT more interesting.
