Since 1941 (the year Citizen Kane was released), the University of Colorado's International Film Series has been a major cultural resource. The inventive CU programmers continue apace in their efforts to bring in exotic and important work. Recently, IFS's "Cult Cinema" series featured screenings of Alferd Packer: The Musical, The American Astronaut and Waking Life; a seven-film tribute to the late Rainer Werner Fassbinder included The Bitter Tears of Petra Von Kant, The Merchant of Four Seasons and Effi Briest, among others. A few upcoming IFS films: To Be and to Have, a lovely French tribute to the teaching profession; Crumb, the too-little-seen biopic about underground cartoonist Robert Crumb, and That Obscure Object of Desire, the surreal classic by Luis Bu?uel.
