Brian Wyzgowski and Dan Finn rehearse a scene from The Port Sanilac Barn Theatre’s season-opening production of “Chemical Imbalance”. This play by Lauren Wilson is a darkly comic adaptation of the Dr.Jekyll and Mr. Hyde story. The show is a fast-paced romp about men and women tightrope-walking the line between aristocracy and depravity, and between the twin spectres of good and evil. Curtain time is 8:00 p.m. on Friday and Saturday, June 10 and 11. Reservations may be made by calling The Barn at 810-479-7739.
