Doubt was originally produced by Manhattan Theatre Club Off-Broadway at Stage I at New York City Center, where it opened Nov. 23, 2004, to rave reviews, and played for 101 performances through Jan. 30, 2005.

According to press notes, Doubt is set "in 1964, the year after the assassination of John F. Kennedy, at a Bronx Catholic School where a strong-minded nun wrestles with her conscience in the face of concerns about one of the priests. Sister Aloysius reveals her initial doubts about the enigmatic Father Flynn to Sister James, an inexperienced but enthusiastic young nun. As her suspicions grow about his inappropriate behavior with the school's first black student, a verbal battle of wills begins and she instigates a relentless campaign to remove the priest."

The play began performances at Broadway's Walter Kerr Theatre on March 9, 2005, opening on March 31, 2005, and that year won a Best Play Tony Award.

Shanley's best known work is the Oscar-winning screenplay for "Moonstruck."
