Nastassja has unfortunately not spoken much on THE MOON IN THE GUTTER since it was booed at the Cannes Film Festival back in 1983. Reports say that the film actually began receiving hisses and cat-calls before it even started playing which pretty much lays out that it didn't stand a chance, no matter its merits.
Here are a couple of short quotes by Nastassja on the film:
"It starts at night. Vaguely, it's about...a man starts staring at this gutter and he fantasizes about this girl-that's me-who got stabbed there. He looked all over the place for her murderer. Every man he meets, he accuses of her murder. They all start to believe his accusations. In the end you figure out that he is the real murderer. Depardieu is the guy. There's lots of plot and it's pretty hard to explain."
"It touches something they don't want to have touched."
