Back in 1979, local filmmaker Trent Harris documented a strange series of events. It started when he met “Groovin’ Gary,” who led him to a talent show in Beaver, which inspired him to make three films. The Beaver Trilogy became a cult classic, and questions have surrounded it since its release. Just who was “Groovin’ Gary,” and what happened to him after the talent show? In a new film, director Brad Besser investigates the mystery behind The Beaver Trilogy. He joins us Thursday to talk about it.
