Eighteen years of smoking has taken its toll on my voice (which was a strong Soprano in my youth), but even I could hit the high notes in "Dulcenera" better than Loren. Listening to both of them was an exercise in cinematic masochism. The line, "to be willing to march into Hell, for a Heavenly cause..." should have been sung with feeling, with depth and breadth and throaty courage. Out of O'Toole's mouth, it sounded like a cat choking on a hairball.
So you thought Rex Harrison was singing in My Fair Lady?
Maybe they couldn't act like they were singing and Harrison can, but Harrison can't sing and My Fair Lady was fine.
Hepburn couldn't sing either, but they dubbed her voice. Not Harrison's, though.
I'm going to stand by my original thesis that it's difficult to make a good movie and not everyone with a camera can do it.
Shalom.
