To celebrate its 50th anniversary, Monty Python and the Holy Grail has returned to theaters. Upon its release in 1975 the comedy received mixed reviews from critics but love from audiences; it had the biggest box-office success of any British film in the U.S. Catching up with King Arthur, his Knights of the Round Table, and their quest for the Holy Grail (the chalice from which Jesus drank at the Last Supper), the movie was shot on location in Scotland, with several scenes around Doune Castle, Glen Coe, and Castle Stalker. The Trojan Rabbit, a plan hatched by Sir Bedevere the Wise to infiltrate a French occupied castle, is one of the movie’s many timeless sight gags. Of course, Bedevere forgets to tell the knights to hide inside. —Henry McGrath
