The actress said she had deliberately shied away from "sex object" status after her Lolita-esque role in Leon, aged 12, prompted a flurry of "weird" letters from men.
"The good-girl image was something I consciously cultivated after Leon," she told Elle magazine.
"There was a lot of controversy about the whole Lolita thing. My parents were super-protective about it, but I got a lot of weird letters. It was really upsetting. I didn't want to be seen as a sex object, so I went in the opposite direction.
"I'm definitely not a prude about sex or nudity, I just don't want to do something that will end up as a screen grab on a porn site."
The star of Closer, Garden State and the Star Wars movies recently played a Hasidic bride in New York, I Love You - the first role that plays on her Jewish heritage.
She explained: "I've always tried to stay away from playing Jews. I get, like, 20 Holocaust scripts a month, but I hate the genre. That was the first thing to come my way that really intrigued me."
The actress is now ready to tackle a comic role. "It wasn't that I didn't want to do comedy, it's just just that I would only get offered girlfriend parts in guy comedies where the woman has to have a job in fashion so that she can have nice clothes, and her goal is always marriage. I'm more interested in finding characters that make me laugh."
