Sevigny and her ex-boyfriend Vincent Gallo hit the headlines in 2003 when her character DAISY performed oral sex on Gallo's BUD CLAY in the flop drama.
The following year, Michael Winterbottom's film 9 Songs - which features a couple having sex for the majority of the movie - was released and given adult film certificates.
Sevigny fumes, "What about 9 Songs?
"9 Songs makes Brown Bunny look like Sesame Street. And yet there's no hullabaloo over that film. I mean, that's what I couldn't understand. That was shocking compared to Brown Bunny."
