Terminator, Deliverance added to U.S. film registry

Arnold Schwarzenegger's deadpan one-liner "I'll be back" will be enshrined for posterity by the U.S. government, as The Terminator joins a host of new additions to the U.S. National Film Registry.

The Library of Congress on Tuesday announced 25 titles joining the growing collection, established in 1989 to digitize and preserve a diverse portrait of American video and audio files.

Tuesday's 25 titles bring the total number of films in the collection to 500.

"The registry helps this nation understand the diversity of America's film heritage and, just as importantly, the need for its preservation,"said James Billington, officially known as the Librarian of Congress.

"The nation has lost about half of the films produced before 1950 and as much as 90 per cent of those made before 1920."
