Movie studio Dreamworks has taken steps to block the sale of pirate DVDs of Shrek 2 through the British courts.
Shrek 2 has become the UK's biggest animated film
A High Court judge extended an injunction against 12 individuals preventing them selling the goods.
Mr Justice Patten said he would continue the injunction until the case goes to trial.
Dreamworks lawyer Tom Moody-Stuart said the pirated copies ranged from those recorded in a cinema on a hand-held camera to high quality ones.
The 12 defendants have not been named in court but it is thought the DVDs were being offered for sale on auction websites such as ebay. They are no longer available following a request from the studio.
None of the defendants appeared at the injunction hearing.
The official Shrek DVD will not be on sale in the UK until 5 November but copies have already begun appearing on bootleg market stalls.
Dreamworks is keen to protect its investment and brand in the film, which has just become the UK's most successful animated film, taking £45.6m since its release.
Its box office business ensured it overtook the previous record of £44.3m set by Toy Story 2.
Dreamworks already has a third and fourth sequel in the pipeline.
