The movie ends without any credits. There's not even a "The end" title card. The final shot just fades to black.
Translation of the opening credits:
Cine Experimental Universidad de Chile and Cinematográfica Tercer Mundo present
Nelson Villagra
in a film by Miguel Littin
"About the childhood, path, regeneration and death of Jorge del Carmen Valenzuela Torres,
who also goes by the names José del Carmen Valenzuela Torres, Jorge Sandoval Espinoza, José Jorge Castillo Torres
a.k.a. El Campano, El Trucha, El Canaca, El Chacal de Nahueltoro."
The long title is separated into a short series of title cards. After that, the cast and crew are listed in a normal way.
