Until a few years ago I had never even heard of this movie. When it was released in 1969 it barely made back 10% of its $11,000,000 production cost.
Thankfully, it is now recognized as the great movie that it is.
One of the things I find most interesting about it is that when it was filmed the town of Eckley was so unchanged that all they had to do was bury power lines and hide antennas. The coal breaker they built for the movie still stands.
My ebay-purchased copy of this movie gets viewed a few times a year and I hope to get up that way sometime soon and check things out.
Lots of history and good bars there.
