Fargo opens with "This is based on a true story" but in the extras the Coen brothers admit they made it all up. It's just a movie and they wanted to test how far they could go with suspension of disbelief by putting that up front.
The urban legend of Takako Konishi was also discredited in the extras, a Japanese office worker allegedly froze to death looking for the buried money from Fargo in Minesota. (She did go to Minesota, but commited suicide there in a place she had visited before)
The Zellner brothers turned the urban legend into a movie Kumiko, the treasure hunter.

I had just started university when I saw THX 1138, I can't remember much of it, other than I found it quite boring at the time. I might look at it differently nowadays. I can't have seen the director's cut anyway, that didn't come out until 2004.
They grey sounds interesting, my ears perked up when I read the reference quality lossless soundtrack recommendation on blu-ray.com
