46. Monty Python and the Holy Grail (1975)
Director: Terry Gilliam and Terry Jones
Screenwriter: Graham Chapman, John Cleese, Terry Jones, Terry Gilliam, Michael Palin, and Eric Idle
Having lost none of its satirical hilarity, the intentionally outlandish Monty Python and the Holy Grail (written, directed, and acted out by the infamous British comedy troupe) never fails to impress with its intelligence and sneaky surprises. At first, the film acts like a spoofy account of the King Arthur and his Knights of the Round Table legend, but an out-of-nowhere cutaway sequence shows a present-day historian being killed by a knight while relaying Arthur's legend on camera.
There are several like-minded clues throughout Holy Grail, but it's not until the closing seconds that the Monty Python gents' little twist reveals itself: The men we've thought to be Arthur, his boys, and their enemies are all just escapees from a loony bin. The paddy wagon and cops that interrupt the wannabe knights' impending battle clear up everything. â€”MB
