On “Skillset,” every guest is an expert. And in every episode, these experts are going to teach us a new way to look at motion pictures. We're going to meet the behind-the-scenes specialists who make movie magic: cat trainers and shark-attack consultants and authorities on ’80s underwear. We're going to send real-life punk singers and barbers to movies about punk singers and barbers to learn the facts behind the fiction. And each week we're going ask our favorite actors about the extracinematic obsessions that have shaped them.
