The sun doesn’t shine much in the Bronx neighborhood where John Patrick Shanley’s powerful film, Doubt, is set. The atmosphere is gray and cold; its melancholy mood is disturbed only once in the film by a fierce wind storm that blows down many of the bare limbs of the convent trees. The winds of change are indeed blowing in the Catholic Church in 1964, and Sister Aloysius Beauvier, the principal of St. Nicholas parish school, seems determined to protect her domain from any corrupting influences that might be in the air.
