So some guy found an original, nearly perfect workprint copy of Manos The Hands of Fate (of MST3K fame) and is working on restoring it so it can be released in high-quality on Blu Ray. Apparently, according to the article, the copy that's been available (and was used for MST3K) is a copy of a copy of a shitty copy or something.
