After Soderbergh returned to Baton Rouge, he wrote the screenplay for "Sex, Lies, and Videotape" on a legal pad during an eight-day cross country drive. The movie tells the story of a troubled man who videotapes women discussing their lives and sexuality, and his impact on the relationship of a married couple. Soderbergh submitted the film to the 1989 Cannes Film Festival where it won a variety of awards, including the Palme d'Or. Its critical performance led it to become a worldwide commercial success, grossing $36.7 million on a $1.2 million budget. The film was considered to be the most influential catalyst of the 1990s Independent Cinema movement. At age 26, Soderbergh became the youngest solo director and the second youngest director to win the festival's top award. Movie critic Roger Ebert called Soderbergh the "poster boy of the Sundance generation". His relative youth and sudden rise to prominence in the film industry had him referred to as a "sensation" and a prodigy. In 2006, the film was selected by the Library of Congress for preservation in the United States National Film Registry, being deemed "culturally, historically, or aesthetically significant" and the American Film Institute nominated it as one of the greatest movies ever made.
