You might call Dax Shepard an unlikely Hollywood star, and he’d probably agree with you. He grew up outside Detroit and moved to Los Angeles for college, where he spent over a decade struggling as an actor before his big break. In this week’s “Sunday Sitdown,” Willie Geist gets together with the actor to talk about that journey to stardom, his latest dream job on Top Gear America and his wildly popular podcast “Armchair Expert.”
