Tonight – check out Six Characters in Search of an Author at the Cowley Theater. Six fictional characters, abandoned by their creator, invade a rehearsal in progress and demand to be brought to life by a new author. But the characters’ existential agenda collides with the more lighthearted ambitions of these theatre artists, whose open rehearsal “audience engagement event” becomes darkly entangled with the characters’ tragic story. This intimate adaptation of Luigi Pirandello’s absurdist classic foregrounds the comedic contrast between melodrama and the contemporary sensibilities of the acting company — all the while asking us to consider just what we believe to be real. LIMITED SEATING. Rated PG-13 for adult language and content.
