Although I've only seen two episodes, I'm an instant fan of a show called Iconoclasts on the Sundance Channel. Each episode is a documentary of two people who are well known in their field, usually in some form adjacent to the arts, but not always. Some are unlikely matchups, some are people who have had a long connection, like Lorne Michaels of Saturday Night Live and Paul Simon the songwriter. Often they talk about ideas and creativity. I highly recommend it! I'll be trying to catch up on all the ones they've aired so far.
