Director Peter Yates'classic 1968 thriller Bullitt starring Steve McQueen and Robert Vaughn and John Ford's dark, revisionist 1962 western The Man Who Shot Liberty Valance are among the 25 films chosen by the Library of Congress for 2007's list of movies entered into the National Film Registry. Inclusion on the list insures these films will be preserved for generations to come. It also precludes TV stations that air them from editing the films. Some of the films included are rather obscure silent titles while others are more offbeat such as The House I Live In , a 1945 short film starring Frank Sinatra in a plea for racial tolerance. Among the more puzzling entries is Back to the Future - certainly an entertaining film, but hardly in the league of many of the others chosen. For the full list click here
