Roberts to play sex store worker

The 20-year-old star will portray a college graduate who ends up working in an adult shop in forthcoming black comedy Adult World.

And Roberts, who recently deferred her studies at Sarah Lawrence College in New York to make more movies, admits she relates to her character's struggle.

She tells USA Today, "It's a quirky coming-of-age story. My character is very smart, but the economy is very bad. So she works at a porn store.

"It's an interesting backdrop because when you're a young person you're always looking for inspiration. But then you find yourself asking, 'How did I end up here?' It's very relevant for young people who are asking themselves, 'What do we do?'"

Adult World will be filmed in New York and is scheduled for release later this year (12).
