Shot by a dude in the theatre so you'd see people get up to go to the washroom and hear people talking. Good times!

Loved it when the "academy" rips came out. Good quality finally!
There's a famous 'Chinatown' DVD of
Star Wars Episode III - Revenge of the Sith. The original dialogue was translated into Mandarin Chinese, and the English subtitles were created by translating the simplified Chinese equivalent back to English, using Babelfish, (the precursor of Google Translate).
The result was
Star War The Third Gathers - The Backstroke of the West. This version of the film used those subtitles for dialogue in the audio track.

I have a DVD of the 2005 King Kong where the subtitles have nothing to do with the movie. It sounds like two high school kids texting each other in detention.
