Mel Gibson's controversial film The Passion of the Christ has topped the list of most-pirated films, a US internet analyst has said.
The Passion of the Christ beat 21 Grams to top the list
Tracking firm BayTSP, which monitors web traffic, said 36,693 copies of the film had been found on the internet during April via file-sharing services.
Gibson's film, released in the US in February, will not be available on DVD in the US until August.
The second-most copied film was 21 Grams, starring Benicio Del Toro.
Hollywood studios are desperately trying to stem internet piracy of films in an effort to avoid a repeat of the economic downturn which has affected the music industry.
New file-sharing technology, including BitTorrent, has made it easier for people to copy files as compressed files, then share them on the internet.
High-speed internet connections, such as Broadband, are also thought to have prompted the rise in film piracy.
BayTSP uses a tracking technology, known as a spider, to find copies of copyrighted material on the internet.
The Passion of the Christ has made more than $375m
(£220m) in the US alone, since its release.
A company spokesman said the Pixar animated feature Finding Nemo, a huge box-office success last year, was the most pirated film in the last 12 months.
