From September 4 through October 24, behind-the-scenes filmmaking images of American screen icons taken by Magnum photographers - including Bruce Davidson, Eve Arnold, Henri Cartier-Bresson, Dennis Stock, Burt Glinn, and Alex Web - will be shown at the Center for Photography at Woodstock's exhibition, "Magnum Cinema."  The exhibition, held in conjunction with the Woodstock Film Festival, includes rarely seen images of such film stars as Ingrid Bergman, Marlon Brando, Marilyn Monroe, Elizabeth Taylor, and Orson Wells, all culled from Magnum's vast archive.  For more information, visit www.cpw.org.
