66. Anna Paquin
Biggest accomplishment this year: Reprising her role as Rogue in the forthcoming X-Men: Days of Future Past
The star of HBO's True Blood has totally escaped the typical pitfalls of child stars, sustaining her success well into her adult years. Now 30 years old, Paquin continues to earn award nominations for both her work on True Blood as well as her work in film. She starred earlier this year in the romantic comedy Straight A's with Ryan Phillippe and Luke Wilson, and later in 2013 will appear in the film adaptation of the crime novel Black Wings Has My Angel. She'll also reprise her role as Rogue, the mutant who can't touch anything without killing it, in next summer's blockbuster X-Men: Days of Future Past.
