On this day, he was asked about the acting skills of former idol, Sohee, who plays a female high school student named Jin Hee.  It appears there is some controversy about her acting in the film, but the director brushed this aside. "I didn't find [her acting] a shame at all," he said. "I'm not even sure from what aspect [her acting] is being called a shame. What I think is that Sohee's image as a singer of Wonder Girls is strong, so talk like that is coming out, but in the movie, there was honestly no problem.  It was not only no problem but I actually thought she did well.  The character was not even one that showed many things, but what I find quite a success is that in the case of Sohee and Choi Woo Sik, it was important for them to show the levity of teenagers.

"Some people state that the conversations between Sohee and Woo Sik didn't seem sincere at all, but that reaction was the response I had envisioned from the start.  The way teenagers act is more light and fresh than sincere, isn't it?  I wanted it to be shown in a way that wasn't too sincere.  That's why I thought the scene of their exit would surprise the viewers even more.

"They'd be more traumatized when they're tossed aside like garbage because the teens they're portraying seem so immature, right?  An effect like that was necessary.  On that note, Sohee and Choi Woo Sik both acted extremely well.  There are many people who saw the movie who chose their exit as one of the scenes that made them sad."

Meanwhile, the movie came out back on July 20 and already 2.1 million viewers have flooded theaters to see the disaster movie!
