Wow! I bought the My Fair Lady DVD the other day (nine bucks at Costco) I have always identified with the Eliza Doolittle character and I never relaized why until I watched it post-transition. It is almost a metaphor for MtF transitioning! The transformation from the street urchin to a lady is almost as amazing as any MtF transformation.
There is even a MtF angle. "Why Can't a Woman Be More Like a Man?"
