Lurking in the shadows, doubt

'The truth makes for a bad sermon. It tends to be confusing and have no clear conclusion." So says Father Flynn from the pulpit of St. Nicholas, the Bronx church where this young and popular priest has set up shop in the fall of 1964.

In Doubt, John Patrick Shanley's crisp, cogent adaptation of his own Pulitzer- and Tony-winning play (tellingly called Doubt, a Parable when it debuted in New York in 2004), the truth is left for the audience to decide.

And while the conclusion isn't necessarily clear, it is unsettling.

Doubt is shot on the same streets where Shanley, here making his second stab as a director, grew up. (His first: the failed Tom Hanks rom-com Joe Versus the Volcano.) It is the year following John Kennedy's assassination, and the midst of the Second Vatican Council, a time of enormous change and upheaval in New York and the nation.

But while Father Flynn is looking to loosen things up in his parish, Sister Aloysius (Meryl Streep), principal of St. Nicholas' parochial school, stands firm in her embrace of the strict traditions of a Catholic education. Draped in a black habit, with an almost comic black bonnet strapped tightly to her bespectacled head, she patrols the halls and classrooms with a watchful eye, dispensing a tap here, a whack there, to keep her mostly Irish and Italian American boys and girls in line.

It is a different boy - Donald Miller (Joseph Foster), the school's first black student - who becomes the focus of the conflict between Father Flynn and Sister Aloysius. The priest has befriended the isolated, unsure Donald. But an impressionable young nun (Amy Adams) has seen things between Flynn and the student that have troubled her, and has reported her concerns to Sister Aloysius.

That seed of suspicion is all Streep's character needs: There will be no molestation of children by priests on her watch, even though she has no evidence that such a thing occurred.

Still, she is sure: "A dog that bites is a dog that bites," she tells Flynn in Shanley's big confrontation scene - a scene, in Aloysius' office, shot at absurdly dramatic angles, with the fierce ring of an unanswered phone going off at a nerve-racking clip.
