Sony Pictures Entertainment has issued a statement regarding reports of Spider-Man 3 piracy:

Contrary to news reports about stolen copies of Spider-Man 3 are being sold illegally on the streets in China, our investigation in China has revealed no case of the film being pirated to date.

Similar hoaxes and false alarms have occurred prior to the release of other major films. We have uncovered examples of Spider-Man 2 being sold in Spider-Man 3 boxes in China. But thus far we can find no instance where Spider-Man 3 has appeared on DVD.

In addition, after an initial investigation of online sites worldwide, we have so far found no pirated copies of Spider-Man 3 on the Internet.

This incident underscores one of the problems with piracy -- people who buy illegal movies often get ripped off themselves.

Spider-Man 3 arrives in theatres on May 4.
