83. Elizabeth Olsen
Biggest accomplishment this year: Receiving a BAFTA Rising Star Award nomination
Did you know that Mary-Kate and Ashley Olsen have a younger sister? And did you know that she's legitimately talented? The 24-year-old Elizabeth Olsen has taken on a number of challenging roles in a short time, including 2011's Martha Marcy May Marlene, a performance that garnered her many film critics associations' awards for Best Actress. If her performances in this year's new releases are anything like her previous efforts, more prestigious award recognition should be in her immediate future.
