Sister Aloysius is certain she is right when it comes to her suspicions about Father Flynn, but is she?

At 7:30 p.m. Friday, the Westside Theatre Foundation will offer “Doubt: A Parable,” at the Strand Theatre, 717 Clay St., and without spoiling the ending, audience members are sure to walk away from the show thinking.

Matt Mitchell takes on the roll of Flynn in the local production and described his character as an articulate man and progressive minded priest.

“He is trying to move away from some of the staunch starchiness of the old church,” Mitchell said, which he thinks is one of the reasons Sister Aloysius has an “ax to grind” with Flynn.

“My character is a bitter old woman who never sees good in anybody, not even children. She gets it in her mind that this priest has done something wrong with no evidence what so ever,” Susan Hadala said.

Both Hadala and Mitchell are seasoned performers, however this will be Mitchell’s first performance at the Strand and his first time on the stage in 17 years.

“Performing at the Strand has been a really enjoyable journey,” Mitchell said, and added that it has been nice to perform in a smaller show, after a reprieve from the stage.

Directed by WTF founder Jack Burns, the play has four characters, Flynn, Aloysius, Sister James played by Kimberly Madson-Thomas and Mrs. Muller play by Cathy Sanford.

“It’s a tight ensemble group, which makes it easier, and the play itself is brilliant,” Mitchell said.

“John Patrick Shanley won the Pulitzer when it first came out (in 2005) and a Tony Award. Several years ago a movie also came out, but I have not yet seen it,” Mitchell said.

“Doubt” was released in 2008, and the film starred Meryl Streep and Philip Seymour Hoffman. It was nominated for an academy award.

The play is set at a church in the Bronx in 1964.

“The crux of the show is really about thinking for yourself and questioning your prejudices and assumptions about other people,” Mitchell said, “because there are volumes unwritten about every person that you meet and you can’t possible know the circumstances that are beyond your knowledge.”

Mitchell added he felt like the playwrights intension for “Doubt: A Parable” were to encourage people to question their realities and their assumptions, and act and speak responsibly.

In addition to Friday’s performance, shows will be offered at 7:30 p.m. Saturday and April 29 and 30.

Tickets are $10 in advance at the Highway 61 Coffeehouse and $15 at the door.
