3. Natalie Portman Can't Keep Away the Cute for Leon
http://youtu.be/JhRW8J3gTuo It's a great first audition for little Natalie Portman, but anyone who's seen Leon: The Professional will notice that she's fairly lively here, when in the film the scene is played pretty low-key and emotional. Still, she hits a home run and gets to star as Mathilda, arguably the finest performance she's ever given to this day.
