So many over the years, I saw all the early movies of people like Reese Witherspoon, Thora Birch, Chrstina Ricci, Natalie Portman, Elijah Wood and Kirsten Dunst, as well as a lot more actors, of the young ones today a lot of people talk about Dakota Fanning but her sister Elle Fanning I think is even more talented. Another name to watch out for is Annasophia Robb who has appeared in Charlie And The Chocolate Factory and The Bridge To Terbethia.
Someone else worth mentioning is Amanda Bynes who had her own show when she was 13, she's very funny and has great comic timing, she's 22 now and has a great career in comedy films ahead of her
