A Lord of the Rings screeningFrodophiles, Tolkien lovers, followers of Middle Earth and Ring questers, unite: It’s a “Lord of the Rings” weekend in New York. Tonight and tomorrow (Oct. 9 and 10) is the big event: a screening of the movie on a 60-foot screen at Radio City Music Hall (7:30 pm) while the complete original score (written by Howard Shore) is performed by a live orchestra. Singers including the Brooklyn Youth Chorus and the Collegiate Chorale will accompany Switzerland’s 21st Century Orchestra. The screening of the 178-minute version of “The Fellowship of the Ring” will include (whew) an intermission, and Maestro Ludwig Wicki will conduct using a laptop computer that will run Auricle, a system that will indicate starting and stopping points as well as tempo. Radio City is located at 1260 Avenue of the Americas (between 50th and 51st Streets; call (212) 247-4777 for more information. For the more aesthetically inclined, an exhibit entitled “The Beginnings of a Masterpiece: Original Manuscripts from The Fellowship of the Ring” will be on view at the Gerald M. Quinn Library at Lincoln Center (113 West 60th Street) through November 19. Forty items will be on display, including Middle Earth calendars; notes about Tolkien's invented languages; plot notes, and original drawings. (A valid ID is needed to enter the Library.) The manuscripts are part of Marquette’s University’s extensive JRR Tolkien Collection; it's the first time these works have been on view in New York. Admission is free; call (212) 636-6538 for more information. Everyone together now: One ring to rule them all….
