You may know him from his role as Murray Bauman in Stranger Things and as Martin in the BBC comedy Fleabag. Brett Gelman has dreamed of being a famous actor since he was a child growing up in Highland Park, Illinois, where he wanted to make the other kids laugh and wound up feeling like an outcast. Gelman has written about his childhood and his neuroses in a book called The Terrifying Realm of the Possible. He’s run into problems publicizing the book after making impassioned speeches about his support for Israel in the conflict with Gaza.  Get ready for a heated discussion (and laughs). “Now What?” is produced with the help of Steve Zimmer, Lucy Little and Jackie Schwartz. Audio production is by Nick Ciavatta.
