Oscar-nominated "Black Swan" director Darren Aronofsky said piracy had made work harder for filmmakers, but he also noted positive industry and government responses to curb the practice.

"It's definitely a problem, and definitely needs a solution," the American filmmaker told reporters Monday at the First Beijing International Film Festival.

Aronofsky made the statement responding to a reporter's question that how would he react once seeing pirated copies of "Black Swan" on Beijing backstreets.

"As a storyteller, it was thrilling to hear that my story was widely seen, but piracy has made movies harder and harder to make as it prevents film producers from recovering costs," Aronofsky said.

But he said there have been positive developments, such as spontaneous distribution, which has allowed for global audiences to see new films faster than ever before.

"And it (Black Swan) is a scary movie. You're better off being scared with other people," he added.

China launched several rounds of nation-wide crack-down counterfeit audio-video products products that had mushroomed in China over the past few years.

Last week, more than 26 million pieces of pirated and illegal publications were destroyed across China to mark the World Intellectual Property Day on April 26, a sign of the authorities' determination to continue the fight against piracy.

Last year, about 6,000 people were convicted for intellectual property rights infringement-related crimes in China, court statistics show.

"Black Swan" is an American psychological thriller directed by Aronofsky and starring Natalie Partman, who won an Academy Award for "Best Actress" for her performance in the film. Aronofsky was also nominated for an Academy Award for "Best Director" last year.
