The Monty Python troupe is at the top of its form in this hilarious assault on religious attidtudes. When the Three Wise Men arrive at the wrong manger on the night of Jesus’ birth, Brian Cohen is unwittingly launched into the role of Messiah. A satirical look at formulaic thinking and blind faith, Life of Brian has become a classic of screwball satire for such singularly unorthodox scenarios as the music-hall rendition of “Look on the Bright Side of Life” that erupts at a crucifixion and such eminently fractured gospel as “Blessed are the cheesemakers.” The brilliant ensemble cast is enhanced by cameos from the likes of Spike Milligan and George Harrison.
