"The Sundance Institute, already an alluring brand name for films, is bringing a snapshot of its creative process in an array of disciplines to New York City. A 10-day series of film screenings, musical performances and theater, as well as discussions with filmmakers and other events, begins tomorrow at the Brooklyn Academy of Music. The Sundance Institute at BAM, as the series is called, is a first-time collaboration between the two institutions and comes as the institute celebrates its 25th anniversary. At the heart of the program are 38 screenings of 14 feature and documentary films and 8 shorts, importing the freshest Sundance Film Festival offerings from Utah to Brooklyn, long before most will be widely distributed, if they ever will."
