They discuss the amazing performance of Tilda Swinton as the authoritative Mason, the commanding directorial style of Bong Joon-ho, and the train car on the Snowpiercer they'd most like to spend time in. Trish also talks about getting her start directing the famous OK GO "treadmill video" for the song 'Here It Goes Again' and what it's like taking over an existing franchise with Pitch Perfect 3. She also shares some fascinating tidbits about the eating habits of polar bears.
