CANNES — Plastic surgery drama “Time” by South Korean enfant terrible Kim Ki-duk will open the Karlovy Vary Film Festival next month.Kim, helmer of “The Isle” and “3-Iron,” serves up a story of a young couple who go to grisly extremes to keep their love fresh. It stars Sung Hyun-ah and Ha Jung-woo. Pic was widely tipped as a Cannes contender this year, but the controversial helmer, who won director prizes at Berlin and Venice, wants to unspool his film at as many Euro fests as possible. “It is to the credit of the Karlovy Vary festival that the work of Kim Ki-duk has been discovered for the public at large. He has been our guest twice,” said fest prexy Jiri Bartoska.
