Our Town, Thornton Wilder’s American classic, draws out what’s meaningful about the mundane happenings of everyday life. Set in the fictional New Hampshire town of Grover’s Corners, the three-act play spans a decade and typically requires a cast of 34 to 38 actors, director Michael Weaver says. That’s far more than Interplayers could even fit backstage. So for this production, eight actors will play the whole town. Interplayers worked with the Wilder estate, which agreed to sanction a production with a smaller cast — as long as not a single line of the play was changed. It’s a classic for a reason, after all.
