The government says it will prosecute to the fullest extent of the law those who have illegally spread Internet copies of the blockbuster Korean disaster movie “Haeundae.”

The Culture Ministry says police have already launched investigations into the initial violators.

The ministry has also asked file-sharing sites to block illegal files of Haeundae. Violators will be subject to penalties, including fines.

A ministry official said online copies of Haeundae are 100 percent illegal and warned netizens that downloading them is no different than acquiring stolen goods.
