In light of the absolutely ridiculous news that "Blue Valentine" has been handed a "NC-17" from the MPAA (a commenter on the indieWIRE article said it best: "America was founded by rebels and puritans, so deep in the nation’s psyche is a respect for violence and a fear of sexuality. The MPAA continues to be a powerful expression of that ass-backwards ideology")... here's a look back at 20 years of box office for "NC-17" rated films. I can' t imagine any of these films would have gotten too much more of a boost if their ratings had been reduced to "R"s, but still, this ain't a pretty list financially (though it does include some excellent films):

1 Showgirls (1995) $20,350,754
2 Henry & June (1990) $11,567,449
3 The Cook, The Thief, His Wife and Her Lover (1990) $7,724,701
4 Bad Education (2004) $5,211,842
5 Lust, Caution (2007) $4,604,982
6 Tie Me Up! Tie Me Down! (1990) $4,087,361
7 The Dreamers (2004) $2,532,228
8 Crash (1996) $2,038,450
9 Bad Lieutenant (1992) $2,000,022
10 Wide Sargasso Sea (1993) $1,614,784
