Luis Buñuel's Mexican films are arguably THE most under-appreciated filmography by a major master of the art of cinema. ENSAYO DE UN CRIMEN was titled THE CRIMINAL LIFE OF ARCHIBALDO DE LA CRUZ for release in English-speaking nations. I would have preferred that the original titled were simply translated to English because it is more relevant and meaningful. It means "Crime Rehearsal". This film is a serio-comic treatise on fetishism, impotence and obsession. It is a perfect showcase for the highly talented actor Ernesto Alonso who delivers a subtly powerful performance. In the 60s and 70s, Alonso became quite famous in Spanish-speaking countries for acting, producing and directing telenovelas.
