King Arthur's quest for the Holy Grail. They poke fun of medieval life as subtle commentary on modern life. They forgot to write an ending.
Monty Python and the Holy Grail is one of those films. If you love it, then you love it. It's iconic within its target audience and arguably the most quotable film of all time. It's silly, clumsy, fun, flawed, but the thing that stands out is how every sketch stands up. No soft spots in the bunch.
Here are things you may not know: the face of god was that of a 19th century cricket player. The chain armor was actually wool and the cast was miserably cold during the shoot. The Enchanter's name was Tim because John Cleese forgot his line. The Terry's Jones and Gilliam directed because nobody else wanted to. They didn't get along.
It's the kind of film I should watch once a year. It's been in my personal library for years. AMRU 5.
