Natalie Portman (Queen Amidala)

Here’s one child star who turned out more than okay: The young star of "The Professional" had some cringe-worthy lines in the prequels but survived with her integrity intact. Post "Star Wars," she made the great cult film "V for Vendetta," nabbed an Oscar for "Black Swan," and won a superhero’s heart in "Thor." Next up: The long-delayed "Jane Got a Gun" (pictured) and "Jackie," in which she’ll play Jackie Kennedy.
