re: Blazing Saddles
One of the funniest scenes is when Mel Brooks in Indian Chief get up rides to the top of the ridge, sees the negro railroad track crew and says, “Ugh, schvartzers”.
That scene was cut from the DVD and dropped into the memory hole.
Around 8 or 10 years ago I bought the Blazing Saddles DVD solely because I figured in a few years you would not be able to buy it as it was released in the theaters or at all as with the Disney film "Song of the South." It looks like I was right. (my copy DID have the "schvartzer" line in it and no cuts that I could notice.
