Penned by Pulitzer Prize finalist and MacArthur “genius” grant recipient Sarah Ruhl, Stage Kiss is a charming and profound comedy about romance and the theater itself. The narrative follows a play-within-a-play, exploring the lines between professional performance and personal passion. When two actors with a steamy past are cast as lovers in an overwrought 1930s melodrama, an infamous stage kiss blurs the boundaries between their characters’ fictional romance and their own complicated reality. $28–30, times vary.
