Two years ago, he built the world's largest file cabinet so director Mary Zimmerman could stick actors, animals, and miniature ecosystems in the drawers for her Notebooks of Leonardo da Vinci. Last year, he pared things down, and recently turned the Berkeley Rep's Thrust Stage into a hallucinatory combination of Hades and a Turkish hammam for Eurydice. While other set designers did some knockout things last year -- double threat scenic and costume designer Annie Smart, for example, with her goofily gothic Mystery of Irma Vep, or Kelly Tighe's cramped and humid antebellum cutaway for Summer and Smoke -- Scott Bradley has been doing some real lateral thinking in his designs. He finds ways to use the Rep's oddly shaped space to his advantage, whether he's running water over everything or punching strange doors and cubbyholes in unexpected spaces. All of which must be a relief after designing sets for the David Letterman TV show, one of his other gigs. Right now he's working with Zimmerman in New York on her new piece, Silk; maybe, like so much of her other work, it will find its way to the Rep and we'll get to see what new toy Bradley has built for her.
