The Big Shave (1968)
This short film is a metaphor for the Vietnam War. A man walks into a meticulously clean and sterile bathroom, concentrating on the polished porcelain and shiny metal motif. He then proceeds to shave. When his face is clean, however, he only continues to shave until he pierces through his skin. Blood covers him and falls around him, the red contrasting the perfect spotlessness of the bathroom.
