When asked how old he was when he started acting, Go Soo answered, "I debuted when I was 21 years old." The actor continued with his story, saying, "When I first came up to Seoul, I acted on stage, but I didn't have any money that time. Since I didn't make any money, I decided to put my stage acting on hold for later and eventually quit. Afterward, I began presenting my profile photo to numerous agencies."
Go Soo continued, "That's when I started shooting for commercials and music videos, which jumpstarted my acting career."
Meanwhile, Go Soo is starring in the upcoming film 'The Tooth and the Nail' based on the novel of the same title by Bill S. Ballinger.
