CC's  Leggy Moll Persona in Singing in the Rain is essentially repeated, as her  Femme Fatale Sexy Death Charm was already type-casted. The essential power of the leg kick is the unleashing of the Feminine Force from the vagina.  Here we see legendary hoofer Fred driven to the ground by CC's force, and to think: Two years a row she dominated the 2 greatest dancers of her generation, Gene Kelly & Fred Astaire.  Nothing like starting out at the top and staying there.
