There entire universes of strange film and video out there that have never come within ten miles of your local Blockhead Video. If one person's trash is another person's treasure, then Shocking Videos is the place to go if you're into SubGenius Badfilms! Check out the film categories offered by this outfit:
Shocking Videos has supplied thousands of videos to obsessive movie fans over the years. And the really amazing part is this: it's entirely managed by one guy! Mark "Remote Control" Johnston (one of the contributors to High Weirdness by Mail) is the genius behind this operation, and he stands behind his reputation. If you order from this guy, you will get what you want from him. Furthermore, if you participate in the newsgroup alt.cult-movies, you're likely to run into Mark (along with other cult movie fans). In the summer of 2005 I posted the following message there:
