I talked with legendary audio drama producer Dirk Maggs for an episode about the history of radio dramas last year-- but a lot of great material ended up on the proverbial cutting room floor. So I’m presenting a full version of our conversation, where we discuss how he brought major franchises like Batman, Alien and The X-Files to audio drama, and how he brought The Hitchhiker's Guide to the Galaxy back to radio. And he reveals a few secrets of audio production on how to trick the brain into seeing what’s not there.
