I've been watching the BBC/ Chanel 4 (Can't remember which) series 'The Dark Side of Porn' which has been fantastic. The last episode was on the infamous 'Animal Farm', which I found the most intriguing. They found some great footage of the girl depicted in said films Bodil Joensen and went a little into Her life, which you really start to feel for the girl. Also it gives a bit of history of the VHS tape, and then the confiscation of porn VHS's and the company Color Climax. 'Animal Farm' is one of those films that has become the stuff of legends. The pacing was perfect, especially seeing as they had a lot of ground to cover. I would also recommend the 'Debbie Does Dallas' episode. Who knew there was so much going on behind the scenes!
Documentary based on the book by Erich Von Daniken concerning the ancient mysteries of the world, such as the pyramids of Egypt and Mexico, ancient cave drawings, the monuments of Easter Island, etc. and the fact that these things and modern civilization could have been influenced by extra-terrestrial visitations hundreds(or perhaps thousands) of years ago.
