By Army Archerd — “IT’S ECONOMIC CENSORSHIP,” John Waters says of the “neuter” DVD version of his “A Dirty Shame,” which bows today in an R-rated version for family-themed chain stores and markets while the original NC-17 “Shame” is in DVD outlets. He reminds he had to shoot “an alternate version of every scene for 4-year-olds. I had to take out every four-letter word.” When the “soft-core” scenes were converted, he claims the result was “more perverted.” Waters is back from a European tour with the original film — with no rating restrictions , claiming, “There was no censorship problem at all in Europe.” He agrees the NC-17 rating hurt domestic B.O. (it only did $1.4 million); however, the world market is solid. Besides, “My movies don’t go away,” he boasts. He’s readying his “Cry-Baby” for B’way and “John Waters Presents Movies That Will Corrupt You” series for the Here! Channel.
