Good dance movies?

Question:

Good dance movies?

What are some good movies about dance? ((especially ballet/pointe)) or flexibility such as contortion or gymnastics?

Best Answer - Chosen by Asker: "White Nights". Mikhail Baryshnikov (ballet) and Gregory Hines (tap) were fantastic!!!
"Mad Hot Ballroom" is a great movie that is a documentary about some elementary schools in NYC starting a ballroom dance program.
"Dance With Me" is another great movie. Chayanne and Vanessa Williams dance Latin dance.
"Dirty Dancing" is a movie that features the grind and ballroom/Latin dance moves.
I agree with another person who posted--movies with Fred Astaire or Gene Kelly are excellent.
