Elizabeth Olsen, younger sister to twin siblings Mary-Kate and Ashley Olsen, has gone from little sis to very talked-about actress. Olsen is in two films that will be shown at the Sundance Film Festival that are getting tons of buzz.

Olsen plays the lead in Silent House, a movie about a haunted house. She will also be featured in Martha Macy May Marlene, a film about a young woman trying to adjust to life outside the cult she’s just escaped.

“To have a lead be an unknown -- it’s kind of a risk for people to take. And so the fact that they took that risk . . . made my year, my life, I don’t know! It was really exciting.”

Olsen, 21, is three years younger than her famous twin siblings. “I think it’s a really weird part of this business,” she said of being chased by paparazzi, something she’s seen happening to Ashley and Mary-Kate Olsen. “When I would go shopping with my sisters when I was younger, it would be dangerous. People would almost get us into car accidents. I just think it’s crazy in general but I want to be an actor.”
