During an interview with E Daily, Choi Woo Shik shared his honest thoughts about taking part in Korea's first zombie film, 'Train to Busan'. 

The actor admitted he was worried about trying out the new genre, explaining, "You know, you can't help but compare it to foreign films. The audience probably has a set image of a zombie movie, so I was worried that 'Train to Busan' will not be able to live up to their satisfaction. But it was a worthless worry after all."
