How Can We Know the Dancer from the Dance?

I just finished watching Strictly Ballroom. I had never seen it before, but I had heard for years how great it is. And it is great, absolutely wonderful. After seeing it, though, and being so moved by it, I thought about how much I also loved Dirty Dancing and even Dancer in the Dark. And, I recently had a conversation with a colleague in which she told me she regularly takes classes in the dance department, just because she loves dancing. I've been doing a little reading about Martha Graham, too. There are probably some new-agey self-help books that say I'm experiencing synchronicity. Maybe. I do think the art of dance is a latent interest I haven't explored yet, which could probably enhance my life in any number of ways. Anyone have any suggestions of dances I should learn, or other good dance movies?
