Flight From Death: The Quest for Immortality. I believe it's available on the internet for free.
It's about the work of Ernest Becker, who despite being a cultural anthropologist by training, was one of the most profound psychologists of the 20th C., especially in his dredging through the "worm at the core" and his re-interpretation of Freud, and synthesis of Freud, Rank and Levi-Strauss. To a lesser extent, the film also focuses on terror management research and its relation to our violence as a species. It's a beautifully done film, and is a great introduction to Becker's work and legacy.
