Kim Dotcom has been labelled a "career criminal'' by Hollywood ahead of a landmark hearing in the internet piracy case.
The Hollywood studios' lead executive in the fight against internet piracy also attacked moves by the Megaupload founder to have the case aligned with a battle for internet freedom.
Motion Picture Association of America vice president for internet content protection Marc Miller said: "The case is not about internet freedom. It is solely about a career criminal and his associates who ran a website that was built upon stealing and distributing the hard work of creators who make creative works that audiences love.''
The briefing by Mr Miller came ahead of a hearing in the United States which could unlock NZ$88 million held in the Hong Kong-based company's frozen bank account. Lawyers acting for Dotcom's Megaupload company has applied to have the case against the company tossed out because it has never been formally served with legal papers.
Megaupload's lawyers have said there is no legal basis for a corporate defendant to be served with criminal papers outside the United States.
