Michael Jackson's Thriller video? Unforgettable. The Muppet Movie? Not so much. But both were among 25 films inducted Wednesday for preservation in the 2009 National Film Registry of the Library of Congress. The 1983 video directed by John Landis is the first music video named to the registry. It had been considered previously, but after Jackson's death, the time was right, said Steve Leggett, coordinator of the National Film Preservation Board. Joining the King of Pop in the 2009 class is the 1979 movie starring Kermit the Frog and Miss Piggy and the 1957 sci-fi classic The Incredible Shrinking Man, among other titles. Congress established the registry in 1989, which now totals 525 films. They are selected not as the "best" films but instead for their enduring importance to U.S. culture.
