A show spokesman told Playbill.com that the three actors—who replace original stars Cherry Jones (Sister Aloysius), Brian F. O'Byrne (Father Flynn) and Heather Goldenhersh (Sister James)—passed around the bug during rehearsal. Producers made the decision that they were all too ill to perform.

Taking the stage at the Walter Kerr instead will be understudies Lizbeth MacKay (Sister Aloysius), Stevie Ray Dallimore (Flynn) and Nadia Bowers (Sisters James).

Adriane Lenox, who won the 2005 Best Featured Actress Tony Award for playing Mrs. Muller, and is the sole remaining original cast member, will perform.

In the lauded play by John Patrick Shanley, four-time Tony Award nominee Atkins has been cast as Sister Aloysius, the sharp, steely nun who runs a Bronx Catholic school and suspects a popular priest of misconduct with a male student. Ron Eldard (Broadway's On the Waterfront and Death of a Salesman) is set to play the charismatic Father Flynn, and Jena Malone will be young Sister James, pulled between her colleagues. *

Doug Hughes directs the 90-minute John Patrick Shanley play. Shanley, Hughes, the producers and Cherry Jones all won Tony Awards for their work on the bracing drama. The play also won the 2005 Pulitzer Prize for Drama.

"Set against the backdrop of a Bronx Catholic school in 1964, Doubt is the story of a strong-minded woman faced with a difficult decision," according to producers. "Should she voice concerns about one of her male colleagues…even if she's not entirely certain of the truth?"

Set design is by John Lee Beatty, costume design is by Catherine Zuber, lighting design is by Pat Collins, original music and sound design is by David Van Tieghem.

Doubt is produced by Carole Shorenstein Hays, MTC Productions Inc. (Lynne Meadow, artistic director; Barry Grove, executive producer), Roger Berlind and Scott Rudin.

The Walter Kerr Theatre is at 219 W. 48th Street.
