Everyman Repertory Theatre will open its production of “God of Carnage” by Yasmina Reza Friday night, Nov. 18, at the downtown Camden Opera House, but the show has already drawn an unexpected audience — the Camden police.

A couple of months ago, as the not-for-profit troupe was rehearsing the contemporary comedy on the opera house’s third floor, the warmth of the evening led to the windows being opened to let in the night air. All was going well and it was decided that we would dispense with the scripted lines and finish the play through improvisation.

“This is a method we often use in the early stages of rehearsal to explore character while following the basic storyline of the play,” said Everyman Rep’s artistic director Paul Hodgson.

Reza’s Tony Award-winning comedy revolves around two couples, played in the Everyman production by Paul and Jennifer Hodgson, David Troup and Laurel Johnson. After their sons get into a playground fight, the couples plan a polite meeting to resolve the matter. Their cordial conversation, however, soon devolves into petty squabbling and chaos as the rum flows and the gloves come off in a savagely funny exchange.

“The play is about adults behaving badly, and contains some strong language as well as being absolutely hilarious, so we were pretty exhausted when the rehearsal came to an end. But nothing prepared us for what would happen next,” said Hodgson.

The company was sitting around having cups of coffee when through the door came two Camden police officers who said they had had a report of a domestic disturbance in the “apartment above the Opera House.” The officers said they knew it was probably a rehearsal but had to respond to the complaint.

“Oh, no, the windows,” said Johnson, who plays Veronica in the show.

“So we explained to them about the show and what the play was about, how it might seem as if there was an actual disturbance. But we were just acting, we assured them. The officer just looked at us and said, ‘Well, you must have been doing a pretty good job,’” said Paul Hodgson.

No charges were pressed, but the visit did make the police blotter. The show is directed by Christina Burz, designed by Dan Dalrymple, lit by Brandon Koons and produced and stage managed by Keith Mackenzie. Jim Reitz worked with Dalrymple on set construction.

Everyman’s “God of Carnage” will be presented Fridays and Saturdays at 7:30 p.m.; and Sundays at 2 p.m. through Nov. 27 in the opera house’s auditorium. Tickets are $20, $10 for students. Tickets are available online at everymanrep.org and from the box office (236-0173), as well as at the Owl & Turtle and HAV II in Camden; Reading Corner in Rockland; and Bella Books & Antiques in Belfast.
