One of the most popular pop culture monsters of the 1970s was the Loch Ness monster, a supposed displaced dinosaur or sea creature in a deep Scottish lake. Nessy even made it into a song by The Police and Napoleon Dynamite. While the Loch Ness monster also seems like a plausible real thing that could exist, it turns out, it's the most likely of the famous 1970s monsters not to be real. This documentary from 2012 takes a look at how the Loch Ness monster turned out to be nothing more than a plot to get revenge on a newspaper.
