Despite the arrival of Twilight: Breaking Dawn – Part 2, South Koreans are hot for a teenage werewolf romp of their own. A Werewolf Boy has become the most-watched homegrown romance of all time with over 6.5 million admissions as of Monday, and the craze has prompted the release of a new version with an alternate ending, reported THR earlier this week.

Jo Sung-hee’s fantasy film, which revolves around a romance between a young girl (Park Bo-young) and a feral yet devoted “wolf boy” (Song Joong-ki), topped the Korean box office for four consecutive weeks from Oct. 31 to Nov. 28, keeping the Hollywood vampire saga – which has been seen by 2.39 million by now – at number two for two straight weeks after its release in the country on Nov. 15.

“Summoned by an unexpected phone call, an elderly woman visits the country cottage she lived in as a child. Memories of a boy she knew 60 years ago come flooding back to her. Then young Suni and her family moved to a small village in Korea. There, they encounter a bedraggled orphan boy hiding under a bush and take him in out of pity. Called a “wolf boy” by some for his feral behavior and uncommon strength, Suni teaches the boy how to eat at a table, and read and write so that he might one day live among people. He repays her kindness with a devotion unequalled by any human being, a love that exceeds all normal expectations. Then one day a threat to Suni exposes the boy’s deadly bestial instincts, and in an instant he becomes the subject of the villagers’ fears. In order to save the boy’s life, Suni must abandon him while promising, “Wait for me. I’ll come back for you.”

At the behest of fans, distributor CJ Entertainment announced Friday that it will release this month in theaters an alternative ending version of Werewolf. Meanwhile, the fantasy flick, which opened Friday in the Los Angeles and Las Vegas regions, is due to hit more theaters across the U.S. and Canada on Dec. 7. Check out the trailer below!
