From the darkness of the church confessional, an anonymous voice reveals the torment he suffered in his youth at the hands of a serially abusive priest. He promises Father Lavelle (Brendan Gleeson) that the Father will be martyred just up the beach the following Sunday to pay for his tormentor’s sins. So begins director John Michael McDonagh’s follow up to “The Guard” (TCFF ‘11), a mordantly comic who’s-gonna-do-it set in a seaside Irish village. The tough-minded, erudite priest has a week to settle his affairs, or change the murderer’s mind. Father Lavelle believes he knows which of his combative black sheep threatened him, even if we do not: is it the supercilious squire, the sad-sack butcher, the baleful publican? Filled with sparkling wit, a deep love of language, a sharp sense of place, and rapid-fire repartee, “Calvary” is a must-see for serious film lovers.
