Actor Lee Seung-gi has pledged to ride the 70-meter high rollercoaster Gyro Drop with 50 of his fans if his upcoming rom-com movie, “Love Forecast,” reaches 5 million viewers. Lee plays Kang Joon-soo, a sweet, unassuming elementary school teacher in love with his vivacious weather forecaster friend of 18 years, Kim Hyun-woo, played by actress Moon Chae-won.

“My character is deathly afraid of heights, and so am I in real life,” he said Thursday during a news conference for the movie. “Director Park (Jin-pyo), however, insisted that the success of the movie hinged on getting that shot of Kang riding the Gyro Drop,” Lee added with a mournful smile. “So I did, and I’d like to share that feeling of terror with my fans if our movie is a hit.” His was not the only high-rise scene in the movie, however; Moon had to go bungee jumping. “It was difficult,” she said brightly. “But I just had this feeling that making that leap would somehow lead to the success of our movie. So I jumped.”“To my eyes, both actors are radiant on the screen,” director Park commented when asked about the filming process. “They exude a sort of natural playfulness that really captures the mood of young lovers.”Directed by Park and starring Lee and Moon, the film opens in theaters on Jan. 14.By Rumy Doo ()
