UNESCO has launched the Memory of the World Programme to guard against collective amnesia calling upon the preservation of the valuable archive holdings and library collections all over the world ensuring their wide dissemination. This film and 'Fritz Lang''s Metropolis are the first two movies (and in 2004, the only two mocies) with this recognition.
Recently a ninth roll off the movie was found after decades of thinking that the movie only had eight. The ninth roll includes an alternative "happy" ending, and is included in a new DVD released in Mexico with a book about the movie.
When it was released in Mexico in 1950, its theatrical commercial run only lasted for three days due to the enraged reactions from the press, government, and upper and middle class audiences.
