“It would be difficult to find a better exemplar of career reinvention than Mikhail Baryshnikov. Of course, he started with a few little advantages, like being one of the most idolized ballet dancers of all time, like being seductively handsome, like having multiple talents and the fame to capitalize on them. He has starred on film and on Broadway and on television. He has choreographed and been artistic director of American Ballet Theater, and founded and starred in his own White Oak Dance Project. But most of his efforts so far have been extensions of his dance career, rather than a transition from it. Now he is overseeing something else, the much-bruited, still almost stealthy Baryshnikov Arts Center.”
