One of my favorite podcasts is The Hollywood Podcast. (Podcasts are basically radio shows that you can subscribe to and download in the form of MP3 files.)

Actor/writer Tim Coyne authors the podcast and creates a new one every week or so. His past episodes have included a wide variety of Hollywood-centric topics -- from following paparazzi photographers as they "stalk" Gwyneth Paltrow, to joining Tim as he auditioned for an episode of Charmed, to trying to save the urban gardens in East Los Angeles. No matter the topic, they're always intelligently put together and interesting. Tim does a great job.
