There's a new "Ultimate Collector's Edition" of "Butch Cassidy and the Sundance Kid". I guess hadn't seen this film in like 35 years or something. It was odd how much of the imagery I remembered after all this time ( I couldn't have been more than 6 or 7 when I saw it, if that old). What a great film. Redford and Newman were such gods back then. There really aren't any comparable movie stars nowadays, I don't think.
And the Bacharach/David score is very memorable (I love their "banjos & whistling" phase), though there doesn't seem to be much in the way of incidental music, just complete songs, usually behind some sort of montage.
I haven't made it through all the commentaries and Special Features yet but it's chock full 'of em, including trailers, making of's, featurettes and documentaries and more. Check it out. Buy Butch Cassidy and the Sundance Kid (2-Disc Collector's Edition)
