The Big Shave [Viet '67] - Martin Scorsese (1967)

The Big Shave, also known as Viet '67, is a 1967 six-minute short film directed by Martin Scorsese.

Wikipedia says:
"Peter Bernuth stars as the recipient of the title shave, repeatedly shaving away hair, then skin, in an increasingly bloody and graphic bathroom scene. Many film critics have interpreted the young man's process of self-mutilation as a metaphor for the self-destructive involvement of the United States in the Vietnam War, prompted by the film's alternative title. The music accompanying the film is Bunny Berigan's "I Can't Get Started", recorded in 1937. The film was produced at New York University's Tisch School of the Arts for a film production class called Sight & Sound Film."
