Joss Whedon must like ballet dancers. He has always hired at least one former ballet dancer (usually professional) as a series regular on all his programs. As a Whedon fan, I've always had fun picking out the dancers among his cast. Summer Glau, mentioned earlier in this thread) got her start in that "Angel" episode, then quickly went on to become a series regular in Whedon's "Firefly." Her character was a genius whose talents included dance. Besides Glau, other Whedon series regulars who were also ballet dancers, either as actual professional dancers or long-time pre-professional students include:
That's interesting - I knew Summer Glau but I didn't realize how many other Whedon actors are from ballet. I heard an interview with Whedon last summer (on BBC radio's Wittertainment) in which he said that he'd like his next project to be a ballet. It wasn't clear if he meant filming a ballet or staging one, but either way, I'd be very interested. I think he'd do a great Coppelia or Giselle. Coppelia especially seems to coincide with lots of his interests (uncanny dolls, magic, strong female central character, etc).
