If you have not seen this film, seriously, you've been deprived.  Monty Python was going strong in the late 60s/early 70s and after the show ended, the team decided to embark on a film project which led to "Monty Python and the Holy Grail."  Released in 1975, this film has stood the test of time and produced many fans around the world and developed cult status.  Monty Python followed up with two sequels ("Life of Brian," "Meaning of Life"), but of the three this comedy marvel is still the strongest.
