Love triangle

Carolyn Jerz of Greensburg, a three-time winner of Pittsburgh Public Theater’s Shakespeare Monologue Contest, will play Viola in Prime Stage’s production of the genderbending comedy “Twelfth Night.”

Viola becomes embroiled in an unlikely love triangle when she is separated from her twin brother after a shipwreck. This marks the first time at Prime Stage for Jerz and veteran actor Art DeConciliis, who plays the jolly drunkard Sir Toby Belch. Directing is Andy Kirtland, artistic director of The Pittsburgh New Renaissance Theatre Company.

It’s at New Hazlett Theater, Allegheny Square East, North Side, Friday through May 12, 8 p.m. Fridays and Saturdays and 2:30 p.m. Sundays (plus 1 p.m May 11). Tickets online and at the door: $25-$30 (check www.primestage.com for discounts for seniors, students, young professionals, military and students); 412-608-2262 and primestage.com.
