One of Australia’s leading visual effects companies, Rising Sun Pictures (RSP), has published a statement saying it had nothing to do with a copy of X-Men Origins: Wolverine appearing on several file-sharing websites.

As reported by yesterday, the upcoming action thriller has since been removed from cyberspace but the FBI and the Motion Picture Association of America are investigating how it was stolen. Some media reports noted that Rising Sun Pictures’ name was visible on the unfinished film, and it was only this that prompted RSP to go public.

‘From the reports we’ve had, the stolen material is a work-in-progress version of the film with many incomplete sections,’ said RSP chair and co-founder Tony Clark. ‘As we worked on individual sequences within the film, neither RSP nor its staff members have ever been in possession of a completed version, so it would have been impossible for the full-length movie to have been leaked from here.

‘It’s common practice for work-in-progress between us and the production to carry vendor watermarks and for those works-in-progress to be integrated into various edits of the film for screenings, which would explain why our name appears.’

RSP has offices in Adelaide and Sydney and is one of the most successful in the country at winning US blockbusters. Its has not just been busy on Wolverine, but also Harry Potter And the Half-Blood Prince and Terminator Salvation.

‘Our security systems are rock solid and it would be commercial suicide if they weren’t,’ a spokesperson told today. ‘What we don’t want is to be implicated by hearsay.’

Wolverine stars Australian actor Hugh Jackman and was filmed in Australia by director Gavin Hood. Local media have been promised exclusive footage this Wednesday prior to meeting Jackman and others at a press conference at one of the key locations, Cockatoo Island in Sydney Harbour.

The film releases in Australia on Wednesday April 29 - most films release on a Thursday - which is before the worldwide release.
