AceShowbiz - Michael Jackson's classic "Thriller" video will go down in U.S. history as a national treasure - the 1983 promo is set to be inducted into the National Film Registry of the Library of Congress. The work of the late King of Pop is the first music video to make it into the archives, which preserves original copies of classic film, TV and other recordings at the Packard Campus of the National Audio-Visual Conservation Center near Culpeper, Virginia.

However, Library officials will have to battle to obtain a copy of the horror video for preservation because it's currently the subject of a lawsuit between music video director John Landis and the tragic star's estate. Landis, who directed and co-wrote the "Thriller" script, filed suit against Jackson in January 2009, claiming he's owed royalties for his work on the video.

"Thriller" will be entered into registry on Wednesday, December 30 alongside 24 other films including 1979's "The Muppet Movie", 1957 sci-fi epic "The Incredible Shrinking Man", "Once Upon a Time in the West" (1968), and "Jezebel" (1938), which starred Bette Davis.
