Around 30,000 illegal copies of the action flick have been sold in dodgy shops and stalls, say officials.
The number's based on the amount of DVDs and videos the Federation Against Copyright Theft (Fact) group have confiscated.
The organisation says it's already seized 1,000 illegal Spidey DVDs and videos, according to the Screen Daily website.
This means there are probably about 30 times as many on the streets and being sold now.
Big prob
It's not just a problem in the UK either.
Top movies recently nabbed in other countries have included 3,800 DVD copies of Men in Black II, which only came out in the US on Wednesday.
And the money-making business of pirating films in the UK is growing at a shocking rate, as the gadgets to do it with get cheaper.
Fact says it's found more than 39,000 illegal DVDs in 2002 so far compared to 8,000 in the first five months of 2001.
