Next weekend, avid moviegoers will all be watching the Oscars. But for those who love ballet or are rooting for "Black Swan" to win the several categories in which it’s competing, the most sought after show this season is the production of "Swan Lake" at Lincoln Center. Too bad that tickets are already sold out to see the real-life Natalie Portman, the prima ballerina of New York City Ballet, Sara Mearns. If you want to try your luck, you can go to the box office in person and see if anyone dropped out on the day of the presentation.
