Also being preserved: an Elvis Presley film and a golden oldie starring Rin Tin Tin (for those of you who don't know: a canine movie star discovered in France during World War I who was featured in two dozen movies).
They are among 25 films selected by the Library of Congress to the registry, which now holds 400 movies.
Also on this year's list: movies starring Popeye the Sailor Man, Our Gang (nine years before Robert Blake joined the cast of the kiddie ensemble series, at the tender age of six), and dance and romance legends Ginger Rogers and Fred Astaire.
Librarian of Congress James H. Billington made the selections after evaluating nearly 1,000 titles nominated by the public and consulting staff and advisers, the library said.
"The films we choose are not necessarily the 'best' American films ever made or the most famous," Billington said in a statement. Rather, they are chosen because they have "cultural, historical or aesthetic significance."
A film's selection recognizes its place in American film and cultural history, he said.
"The registry stands among the finest summations of American cinema's wondrous first century."
This year's selections span a wide cinematic range and include both obscure and well-known movies. Among the better-known films:
Lesser known films on this year's list include "Daughters of the Dust," the first feature-length film by an black woman to receive a wide theatrical release, and "Empire," Andy Warhol's eight-hour, one-shot stationary camera look at the Empire State Building.
The registry was established by Congress in the 1988 National Film Preservation Act, and each year, 25 movies are added. The Library of Congress works to ensure that each film in the registry is preserved for all time.
