The Medford Public Library kicks off the Halloween season with a showing of the 1972 cult classic “Night of the Lepus” in Bonsignore Hall at the Charlotte & William Bloomberg Library building. In the film (rated PG), an experiment gone wrong leads to a night of terror — and giants rabbits — in a small town. Doors will open at 6:30 p.m., with the movie (88 minutes) starting at 7.
