Park's vampire thriller Thirst and Bong's Mother, about a woman attempting to prove her son's innocence after he is accused of murder, have both been sold to Romania's Independenta.
Both titles should be ready in time for Cannes. Focus Features co-produced and will handle North American distribution of Thirst, while Diaphana acquired French rights to Mother at the AFM.
In addition, CJ has sold Haeundae, a disaster movie about a super-tsunami heading straight for the Korean seaside resort of Pusan, to Turkey's Horizon International and Intersonic for the Czech Republic.
Horizon also snapped up completed action thriller Marine Boy, about a swimming instructor-turned-drug trafficker who swims across the ocean with illegal drugs.
CJ also sold The Good, The Bad, The Weird, which has already been sold to more than 20 territories, to Discovery for ex-Yugoslavia. Australia's SBS acquired library titles Black House and Secret Sunshine.
CJ sales chief Mike Suh said he was happy with the company's new EFM location at the Marriott hotel: 'We've been able to catch up with the major buyers and closed some deals every day.'
