Monty Python and the Holy Grail
And now! At Last! Another film completely different from some of the other films which aren't quite the same as this one is.
Overview
King Arthur, accompanied by his squire, recruits his Knights of the Round Table, including Sir Bedevere the Wise, Sir Lancelot the Brave, Sir Robin the Not-Quite-So-Brave-As-Sir-Lancelot and Sir Galahad the Pure. On the way, Arthur battles the Black Knight who, despite having had all his limbs chopped off, insists he can still fight. They reach Camelot, but Arthur decides not to enter, as "it is a silly place".
I’ve never expected a 1975 movie to look this fresh. It rivals and tops many modern comedies. It’s intelligently stupid and hilarious, which is quite an achievement of the director. From just reading the script, I’d say the movie would be stupid and dull, but everything just works here. On top of being funny, this movie also has an adventure spirit with an accurate recreation of the Middle Ages. Well done.
