Christopher Lloyd is a little like Michael Caine in that he's a working actor who pretty much always has a slew of projects lined up. However, most people probably know him as Dr. Emmett Brown ("Doc") in the Back to the Future series, or from the late-'70s TV show Taxi.

Since late February Lloyd has been spotted in Virginia, Minnesota, posing with fans and patronizing various businesses. He's in town shooting an indie flick through mid-March. The crew is moving to Minneapolis sometime next week.
