Good films ABOUT dance or films involving good dancing?
If the former; The Company, Shall We Dance (either 1936 Fred & Ginger or the more recent Japanese film), Follow the Fleet, An American In Paris

If the latter; The Band Wagon, Top Hat (indis-fucking-putably so), Step Up, Singin' In The Rain and obviously Dirty Dancing.

Off the top of my head.
