Every winter, 8,000 feet above sea level in the Utah snow, the hopes and dreams of young moviemakers are put on display at the Sundance Film Festival--the haven for independent films where you can show up a kid and go home a star.

In barely twenty years of existence, the festival--now overseen by Robert Redford's Sundance Institute--has assumed tremendous importance for today's film culture: during the annual ten-day event, tiny Park City is so overrun by agents, publicists, studio executives, and other Hollywood types that in 1988 they blew out the town's cell-phone relay system.
