From the time they were teenagers playing around in their dad’s TV studio, Andy Erwin and his brother Jon knew they wanted to combine their faith with entertainment. Since the days of producing music videos, their career has exploded, with movies like “I Can Only Imagine,” “I Still Believe,” and now, “The Jesus Music.” Andy shares with 9-time Emmy winner David Sams about the personal growth he’s experienced with each project and the excitement of their upcoming Christmas Day theatrical release, “American Underdog.”
