Not sure if this has been posted but I ran a search and did not see anything... Anyway for those of you that have Amazon Prime Video there is a documentary on Ed Roth. I found it quite entertaining. Highlights include the Outlaw and Mysterion. https://www.amazon.com/Tales-Rat-Fink-John-Goodman/dp/B07YNZJDDS
I bought the video when it came out. In fact I somehow got in touch with Ron Mann while he was creating the show ( don't remember the details) and gave him a lot of encouragement to git 'er done!
