Customs officers have demanded an explanation from the film industry after seizing copies of two newly released local movies. Ben Leung Lun-cheung, deputy head of the Intellectual Property Investigation Bureau, said the video compact discs seized in two separate operations were manufactured in local plants and destined for overseas. 'We could not take any legal action because they were legal copies. And we have to hand them back to the shops later,' Mr Leung said. 'We were confused because the seized discs were just like pirated copies. 'Printing of the legal discs was rough and their packaging was not good. 'Like pirated discs, they were just packed in transparent plastic bags rather than in plastic cases.' Under film industry practice, copies of a movie can only be manufactured three months after a film has premiered, Mr Leung said. The Customs Department has written a letter demanding that the Hong Kong Motion Picture Industry Association immediately explain the situation. Mr Leung also said that during the recent raids, four registered plants were found. They were manufacturing copies of local films legally but the movies had not been released to cinemas. Mr Leung said the price of legal video compact discs would range from $30 to $100. Yesterday, Customs officers displayed $1.94 million worth of pirated compact discs found hidden in cargo that arrived from Malaysia via Singapore last Saturday. The consignment, declared as blank discs, included 86,000 pirated copies of a Japanese drama series, 19,000 pirated music discs and television game discs and 57 disc replication stampers. No one has been arrested.
