Paul Nicklen has spent decades documenting the Arctic, Antarctic and the effects of climate change. He talks about some of the dangerous situations he's been in while on the job. "I'm not really scared of death, I just want my death to be cool, and I guess being speared by a narwhal would be a pretty cool way to go." (Originally broadcast in June 2017)
Also, film critic Justin Chang reviews 'Luce.'
