Actor Kim Yoon-seok denied rumors that he had an argument with director Na Hong-jin during the filming of the movie "The Chaser."
Kim appeared on tvN's "You Quiz on the Block," broadcast on the 11th, marking his first variety show appearance in 39 years since his debut. On the day, host Yoo Jae-suk asked about the situation at the time, stating that there is a story that Na Hong-jin and Kim "had a confrontation" because they filmed without sleeping for 40 hours during the production of "The Chaser."
Kim replied, "I was very close with director Na Hong-jin. We laughed among ourselves, saying 'there are all kinds of rumors out there.'" He added, "Director Na Hong-jin is someone who would say, 'Why are you doing that, hyung?' if I said, 'Yap!'"

What Kim Yoon-seok and Ha Jung-woo filmed over the course of 40 hours was the final duel scene of the movie. Since both actors were wearing blood makeup, they had to start the makeup process all over again the next day if filming was interrupted. It was also reported that matching the continuity with previously shot scenes was no easy task.
Kim said, "It was more difficult to redo the blood makeup," adding, "Ha Jung-woo and I decided to 'just shoot it through to the end.'"
The rumor of a fistfight between the two originated from an anecdote revealed by director Na in an interview with the film weekly magazine "Film 2.0." Director Na stated that early in filming, while shooting a scene where Kim Yoon-seok was waiting inside a car, they had a shouting match due to differing opinions on hand movements and eye contact, which even led to a light fistfight. According to director Na, Kim Yoon-seok called him the next day and said, "I think you were right."
Kim Yoon-seok and Ha Jung-woo later worked together again in director Na's film "The Yellow Sea." Kim mentioned that director Na wrote the screenplay with him and Ha Jung-woo in mind, stating, "In 'The Chaser,' I was running constantly, but in 'The Yellow Sea,' Ha Jung-woo was running constantly. After reading the script, everyone except Ha Jung-woo laughed."
