"Singin' in the Rain" (1952) Gene Kelly had what Fred Astaire didn't: sex appeal. This is why "Singin' in the Rain" is still a thrilling dance movie to watch more than 50 years later. "Ladies and gentlemen, stop that girl, that girl running up the aisle. Stop her! That's the girl whose voice you heard and loved tonight. She's the real star of the picture. Kathy Selden!"
One of the most under appreciated dancers of his time, Donald O'Connor had the great dance skills and the comedic timing to make him one of the best ever filmed. Best evidence is Moses Supposes with Gene Kelly and Make 'Em Laugh both from Singin' In The Rain.
