SEOUL, South Korea >> A South Korean activist says he will launch balloons carrying DVDs of Sony’s "The Interview" toward North Korea to try to break down a personality cult built around dictator Kim Jong Un.

The comedy depicting an assassination attempt on Kim is at the center of tension between North Korea and the U.S., with Washington blaming Pyongyang for crippling hacking attacks on Sony Entertainment. Pyongyang denies that and has vowed to retaliate.

Activist Park Sang-hak said Wednesday he will start dropping 100,000 DVDs and USBs with the movie by balloon in North Korea as early as next month.

If carried out, the move is expected to draw a furious response from North Korea. The two Koreas traded gunfire in October over propaganda balloons.

Park says the ballooning will be done clandestinely.
