Producer John Mitchell is a Wisconsin native who left for L.A. and returned two decades later to make a documentary showcasing his home state and its special culture, history, and appeal. Called "Cheeseheads: The Documentary," this in-depth, sometimes personal, often humorous look at the state shows why the "Cheesehead" is more than just a funny foam hat. It's out now, and we talk with him about Wisconsin, making this documentary, and what makes this state so special.
