When seeking out subjects for a documentary, Steve Heminover is exactly the kind of person you want for your film. He's a member of that subset of scientists who are personable, have good camera presence, and are charismatic as well as knowledgable. There aren't many out there, which is why you see a lot of the same scientists crop up in TV science documentaries. Michio Kaku, Bill Nye, and my our personal favorite/patron saint of the show, Neil DeGrasse Tyson. Steve Heminover should be added to this list. Our interview with him was delightful, and the camera only seemed to make Steve goofier and more gregarious.
We filmed his interview in his workspace. Steve owns a company called Aura Technologies, which specializes in many things, but mostly does laser shows for Chicago-area events. If you've seen a laser show at the United Center, that's him.
