Harbour talks about working alongside teen actors in 'Stranger Things,' and his bipolar disorder. "Acting allowed me to channel this neurosis into a character," he tells 'Fresh Air' producer Sam Briger. Harbour plays the skeptical police chief of a sleepy town besieged by supernatural events in the Netflix series.

Also, we remember late 'New Yorker' cartoonist Gahan Wilson. When Terry Gross spoke with Wilson in 1986, he told her he was fascinated by monsters and thought they were great metaphors for human fears and weaknesses.
