George Ratliff talks about his Christian Haunted House documentary, Hell House, on This American Life from 2002, being made available to listen to and download currently. I am a huge fan of both the actual Hell House in Cedar Hill, Texas and of the documentary. Thanks to Brother Steve for spotting this!
If you've never seen the doc, I suggest you go immediately to the Snake Oil Amazon Store and pick it up while it's still available.
UPDATE: Hell House Lives!
