Marc Maron has nothing to prove as a stand-up comic or as a podcaster, but he’s still stretching his wings as an actor. He’s terrific in director Lynn Shelton’s entertaining new movie Sword of Trust, which just debuted at South by Southwest in Austin, Texas. That’s where Leonard and Jessie talked to them both before an enthusiastic audience at Esther’s Follies. Lynn explains how she combines scripted material and improvisation. Marc is in top form and that’s about as good as it gets!   Fair warning: you’ll hear more f-bombs than usual in this episode.
