Here's a clip from the press release:
In this special two-hour documentary by Madblood director Rachel C. Hunter, cast members Jerry Harrell, Mike Arlo, Penny Palen, Craig T. Adams and Carter Perry narrate and tell stories about the local institution that is the Doctor Madblood show. Covering the entire thirty-year history of the doctor's exploits in Pungo and beyond was a daunting undertaking, but the result is a program as unique and entertaining as Doctor Madblood himself. There are interviews with crew members and longtime viewers, a tour of the current set with its array of one-of-a-kind props and custom-made bric-a-brac, and, of course, choice clips from past and present episodes, some of which have not seen the light of day since they first aired. This is an event not to be missed!
Don't know who the esteemed Dr. Madblood is? Then you don't know what you're missing! Check out his site here (the good doctor also pod-casts, so check that out!).
Anyway, straight from the Muir movie/tv blog to Dr. Madblood himself: Happy 30th Anniversary!
