Elizabeth Olsen will star as Juliet in an off Broadway production of William Shakespeare's 'Romeo and Juliet' later this year.The 24-year-old actress will make her on-stage leading role debut as Juliet in the Classic Stage Company's production, which will open the company's 2013-14 season later this year, according to E! News.Although Elizabeth's older siblings are actresses and designers Mary-Kate and Ashley Olsen she previously insisted they never tell her how to behave or get ahead in her career.She said: "It's always felt as though Mary-Kate and Ashley have been women, while I've been the kid. But we're very close and I look up to them a lot. I wasn't really affected by their fame until I went to college. People would expect me to be partying and all sorts of stuff. It was really strange."We've never had a conversation about [fame], but I learn by example. They try to keep their lives private and they work their asses off. People have this idea of them swanning around the world, partying, but they're at an office every day - I wouldn't be able to do what they do. They have so much pressure on them. They tell me, 'It's all about being happy with what you're working on and trying to be the best at it that you can be.' "
