Original Practice Shakespeare Festival brings “The Merry Wives of Windsor” to Esther Short Park, West Eighth and Columbia streets, Vancouver.

The production uses the techniques used during the Bard’s time: limited rehearsal, an on-stage prompter, audience interaction and fast-paced acting. Catch a bit of Shakespeare starting at 2 p.m. Sunday. Admission is free. www.opsfest.org
