Kim Dotcom is describing the Hollywood film studio case against his former Megaupload company as a load of nonsense and a science fiction script.
Major studios Disney, Paramount, Warner Bros, Columbia, Universal City Studios and 20th Century Fox have launched a case against the now-closed website and three of its key executives, including Mr Dotcom.
The companies claim that the website was a commercial online hub for providing their work to millions of users without authorisation or license.
Their lawsuit alleges the Megaupload website encouraged users to upload popular content, which was often copyrighted material. The studios say Megaupload made $US150 million through subscriptions, and a further $25 million through advertising.
Using Twitter to reply, Mr Dotcom said on Tuesday the claims in the court documents are stupid and simply not true.
In the documents, the film companies say Megaupload chose not use any technology to prevent copyright infringements, and in fact the company's business model depended on copyright breaches.
Mr Dotcom's US-based lawyer, Ira Rothken, said rewards weren't paid out when uploads were bigger than 100 megabytes, which isn't enough for a film. He said when the rewards were stopped, it had no impact on the website's traffic, and therefore the system had no effect on anything related to piracy.
