I have seen Loose Change, Grizzly Man, and the Summit. All were really good, I want to see Paradise Lost.. that looks intense.
Island of Lucifer is probably my favorite because, out of all of them, it’s the hardest to believe. After we watched it, I had to do a lot of research to prove to my GF that it’s real! She just didn’t believe it until I pulled up some wikipedia pages.
I’ve always found it kind of amusing that the director of Paradise Lost – a genuine documentary – was hired to direct a sequel to Blair Witch – a mockumentary – and then approached it by making a traditional narrative film in which the first movie actually existed AS a mockumentary, but inspired by events real within the second movie’s diegesis.
