WASHINGTON, DC – Bambi, Forrest Gump and Hannibal Lecter have at least one thing in common: Their cinematic adventures were chosen by the Library of Congress to be preserved in the world’s largest archive of film, TV and sound recordings. The registry began in 1989 under an act of Congress and now includes 575 films. Its aim is not to identify the best movies ever made but to preserve films with artistic, cultural or historical significance. Previous titles chosen range from “The Birth of a Nation” to “National Lampoon’s Animal House.” A majority of the 25 titles chosen this year for inclusion in the National Film Registry are lesser-known — including silent films, documentaries, avant-garde cinema and even home movies. The Library of Congress announced the selections Tuesday. Films must be at least 10 years old to be considered for the registry. Among the lesser-known titles chosen this year, “A Computer Animated Hand” (1972) by Pixar Animation Studios co-founder Ed Catmull was one of the earliest examples of 3D computer-generated imagery. The one-minute film shows a hand turning, opening and closing.
