Elizabeth Olsen
Age: 22
What She's Done: The younger sister of Mary-Kate and Ashley Olsen, Elizabeth made her acting debut in one of her sisters's early videos. Following graduation from NYU's Tisch School of the Arts, Olsen took to acting in a major way, landing roles in three festival favorites, including 'Martha Marcy May Marlene.' That film, which stars Olsen as a refugee from a cult, earned rave reviews at Sundance and has put the young starlet in the thick of the Oscar race. She also co-stars in 'Peace, Love and Misunderstanding' with Jane Fonda and the horror thriller 'Silent House,' both due out this year.
What's Next: Being one of 2011's It-Girls, Olsen has a plethora of projects lined up. She's set to star opposite Robert De Niro in 'Red Lights,' plays the female lead in 'Liberal Arts' ('How I Met Your Mother' star Josh Radnor's directorial follow-up to 'happythankyoumoreplease') and is attached to co-star with Dakota Fanning in 'Very Good Girls,' about two high schoolers looking to lose their virginity.
Did You Know? Olsen has an older brother named Trent, who also appeared in some Mary-Kate and Ashley videos.
