John Patrick Shanley adapts his own quick and dirty stageplay about a hardheaded nun (Meryl Streep) who suspects a genial priest (Philip Seymour Hoffman) of you know what in racially segregated 1964 New York. Streep and Hoffman contribute mightily to the acting fireworks, though some may find their work too far over the top. It isn't. Instead, this minimalist, catfight is like acting bouillon--drama boiled down to its salty, mano-a-mano essence. 104 minutes PG-13.
