Jang Hang-jun on '옥탑방의 문제아들': 100+ daily decisions, prop colors, shoe angles — the life of a 10M-ticket director

Director Jang Hang-jun sat down on KBS 2TV's 옥탑방의 문제아들 and walked through what it actually takes to run a film set.

"As soon as the car stops in the parking lot, assistant directors rush over," he said. The pace never slows. Once cameras roll, it accelerates: "During filming, over 100 questions pour in per day." Prop colors. Shoe angles. Every micro-detail lands on the director's desk. He compared the pressure to something even the greats struggle with: "It's a phobia that many world-class masters also experience."

The episode also pulled Yoon Jong-shin into a conversation about the cost of early visibility. Yoon debuted as a guest vocalist for 015B and deliberately stayed off TV through his second album. His reason was direct: "There's a story that the upward trend dropped sharply after appearing on a music broadcast." Showing up with visuals that didn't match his voice likely disappointed fans who had only heard him sing. Kim Jong-guk backed the logic. "If you go on TV, your album sales could stop."

(The idea that staying off-screen was a calculated move, not just shyness, hits different when you hear it from people who lived it.)

옥탑방의 문제아들 airs every Friday at 9:40 PM on KBS 2TV.
