In the 1972 British horror film Death Line (released in the U.S. as Raw Meat), Donald Pleasence gives one of his best performances as Inspector Calhoun, an alcoholic, somewhat fascistic detective who discovers evidence of cannibals in the London Underground.  Since the British government would rather this information not be revealed, a mysterious man played by Christopher Lee is sent to discuss things with Calhoun.

This scene features a meeting between two icons of horror so, of course, I love it.  Pleasence is wonderfully obsessive and Lee is wonderfully menacing.  Since the film is as much about the class struggle as it is about cannibalism, it’s interesting to see the automatic conflict between the working class Calhoun and the definitely upper class character played by Christopher Lee.
