Alas, we are prisoners of our animal nature and cannot escape the enslavement of passion, says an elderly village curate to a local aristocrat in Polish-born director Walerian Borowczyk’s deeply weird Gothic-erotic-farcical fable “The Beast,” a film made in France in 1975. (It’s an adaptation of the same material that fueled Jean Cocteau’s “Beauty and the Beast,” and for that matter the Disney version too.) The old priest ought to know; he travels everywhere with two beautiful adolescent boys who do not seem strictly necessary to his clerical duties.
