8. JUDY GARLAND
The Wizard of Oz (1939)

We all know The Wizard of Oz is chockful of heart, brains, and courage, but the girl who made the whole thing dance was Garland. The 17-year-old had big shoes to fill working alongside old pros like Jack Haley (Tin Man), Ray Bolger (Scarecrow), and Bert Lahr (Lion), but her wide-eyed innocence and powerful voice are what truly brought the film over the rainbow. (They also helped land Garland a specially created Juvenile Award at the 1940 Oscars, a kiddie-table honor that's no longer passed out.) Later in life, Garland would lose the innocence and concentrate more on her singing career. And though she could still light up a screen on occasion (most notably in 1954's Star Is Born), to find one of cinema's most indelible performances, you must backtrack down the yellow brick road.
