Just an aside,really:
You notice how sparsely Gene Kelly's finest numbers are shot? Long takes,little in the way of cinematic flair? Well,ponder this for a moment-he will often do something truly spectacular at the end of a take,leading one to wonder just how many times the poor chap put himself through the preceding minutes before getting it right...
A case in point is the justly famed (among those in the know) "Rollerskate Number":In order to demonstrate that the skates are,indeed,authentic,Kelly will swap-flawlessly-from "tap" to "glide" at the end of each take.
Incredible.
Compare and contrast,by the way,with protege Donald O'Connor's emulation in "I Love Melvin"-we never see thetwo movements co-existing within the same shot.
Gene Kelly made me want to dance when I was 11,and not feel like a poof for doing so.
