"I Am Joaquin" the film produced by Teatro Campesino in 1969, based on the epic poem written by Rodolfo Corky Gonzalez in 1967, was selected to 2010 National Film Registry of the Library of Congress.
From the website: Under the terms of the National Film Preservation Act, each year the Librarian of Congress names 25 films to the National Film Registry that are "culturally, historically or aesthetically" significant, to be preserved for all time. These films are not selected as the "best" American films of all time, but rather as works of enduring significance to American culture.
The selection process is kind of democratic, "...the Librarian after reviewing hundreds of titles nominated by the public (this year 2,112 films were nominated) and having extensive discussions with the distinguished members of the National Film Preservation Board, as well as the Library’s motion-picture staff. The Librarian urges the public to make nominations for next year’s registry at the Film Board’s website.
Other films added this year included: Malcolm X (1992), Empire Strikes Back (1980), Saturday Night Fever (1977), Airplane! (1980), and Let Their Be Light (1946) which was banned by the War Department for 35 years because it shows the psychological trauma of soldiers without hiding their identities. One of the first films ever made in America by folks at the Edison company (and you heard he was Chicano) Newark Athlete (1891)
