El fin de la noche (English: End of the Night) is a 1944 Argentine film of the classical era of Argentine cinema. It is notable for being an anti-Nazi film made in neutral Argentina during World War II and set in occupied France. Shot from August to November 1943 in Cordoba Province, the release was put on hold for more than a year, pending authorization by the pro-Axis military government of that time. The film is also remembered in Argentina for Libertad Lamarque's performance of the tango Uno, composed by Mariano Mores and Enrique Santos Discépolo.
