Weirdumentary examines over 45 movies, positioned as documentaries, that began with Chariots of the Gods (1970) and ended with The Man Who Saw Tomorrow (1981). Relying on spurious experts, questionable evidence, and low-budget dramatisations, these pseudo-scientific documentaries examined subjects ranging from the Bermuda Triangle to Bigfoot, from the paranormal to speculative histories. And they made millions of dollars from Americans who repeatedly bought tickets to them at movie theatres. Weirdumentary features a fun and accessible history of these crazy films, individual entries on all of them, and a plethora of fantastic images. Weirdumentary is a must for fans of the cinema, of pop culture, of the 1970s, and of UFOlogy, the paranormal, cryptids, and all things weird!
