He further revealed using different methods to fulfill the requirements of the process,

“We didn’t have many photos of him when he was younger, so we drew image models.”

A Killer Paradox director Lee Chang-hee used deep fake and CG effects in the series

On February 14, Lee Chang-hee attended an interview with South Korean reporters at a Café in Jung District, Seoul. During the interview, he opened up about how A Killer Paradox achieved the similar looks of Son Suk-ku to the child actor Kang Jee-seok through CG effects.

Son Suk-ku played the role of Detective Jang Nam-gam who investigated the murder case involving Choi Woo-shik's Lee Tang. Meanwhile, Kang Jee-seok played Jang Nam-gam during the middle school era in episodes 7 and 8, and another child actor Jang Ji-an portrayed the youngest version of Jang Nam-gam. The child actors garnered attention for their resemblance with Son Suk-ku.

The director revealed that Kang Jee-seok's part and other characters’ looks and appearance in the scenes from the past were modified with the help of deep fake technology. Kim Yo-han’s Noh-bin along with Lim Se-joo who played the role of Gyeong-ah who underwent a plastic surgery in the drama was also showcased through special effects in their past versions. This was one of the reasons why the past versions had no dialogues.
