"After the trailer and music video were released, a close friend reached out to me, joking, 'What’s up? Are you short on cash these days?' Ha ha. I thought that comment carried a lot of meaning. I expected reactions like that. I thought, 'Oh, this is going to be fun.' There were a few projects I chose thinking people would be surprised, but I think this one will surprise them the most. It feels like a pleasant betrayal," Kang said.
To convincingly portray Hyun-woo, Kang learned to dance. Although he is accustomed to action roles, dancing required a completely different skill set. He practiced late into the night even after filming wrapped.
"I was really satisfied with how I looked dancing. By the time we filmed the final stage, I thought, 'Wow, I’m actually good at this.' I worked really hard. Even after filming, I kept practicing and would go to the studio at night. As I continued to film the dance scenes, I gained stage experience. At first, I was overwhelmed with singing, dancing, looking at the camera, and engaging the audience, but later, as the choreography became second nature, I focused more on enhancing my lines. My dance lines improved over time," he said.
While action and dance both involve physical movement, Kang found the training for each to be entirely different. He had a background in martial arts from a young age, but hip-hop dance required rhythms and attitudes he had rarely encountered.
"Learning something is similar, but this felt like a completely new sport with no foundation. I had a bit of a base from practicing taekwondo as a child, but hip-hop was different from dance. Matching the beat felt very unfamiliar. At first, I was learning the moves and thought, 'This isn’t working. I need to start with my steps,' so I spent about 30 minutes just walking. I played music and walked with a friend who was teaching me," he explained.
He immersed himself in hip-hop culture to better understand Hyun-woo. Although Kang typically does not favor method acting, he felt it was necessary to change his wardrobe for this role. It was not just about mimicking a culture that felt foreign to him but understanding the gestures and movements that came from it.
"I had to use a lot of swagger in my gestures, but for those who don’t listen to hip-hop, it can seem confusing. It took me a while to adapt. Eventually, I bought clothes that fit the style. I’m not a fan of method acting, but I felt I needed to wear those clothes to understand the culture. I didn’t get why they walked or moved that way, but later I realized it was all about the beat," he said.
Kang also took the time to study hip-hop history. He admitted he was almost completely ignorant about the genre. By watching documentaries and following the trends of music and culture, he began to understand the environment in which Hyun-woo grew up.
"I didn’t listen to hip-hop much. The only thing I knew was Limp Bizkit. I didn’t even know Tupac was a person’s name. Ha ha. I was so uninformed that I had to start studying hip-hop history from scratch. I watched documentaries, and that’s when I started to understand the character of Hyun-woo. I thought, 'He must have been exposed to this kind of music and lived like this during that time,'" he said.
Kang was particularly focused on the performances of Triangle during their first album. He did not want to trivialize the stage in a comedy film. Instead, he aimed to perform well enough that even actual dancers from that era would not feel embarrassed watching it.
"For the first album stage, my goal was to perform well enough to be funny. I wanted to ensure that those who transitioned from being dancers to singers wouldn’t feel embarrassed watching it. I wanted them to think, 'Yeah, I used to do that,' rather than 'I never did that.' I hoped the audience would feel, 'Why is this so good? Why is it funny because it’s good?'"
'Wild Thing' does not aim for precise historical accuracy but rather blends the cultural sensibilities of the late 1990s and early 2000s into a cinematic experience. Kang expressed a desire to revive the authentic 'coolness' of that era without mocking it.
"I wanted to recreate what I saw on TV when I was in high school. It was genuinely cool back then. I never thought about becoming a dance singer, but I wanted to capture that feeling I had as a child. I wanted to incorporate the essence of first-generation idols. I didn’t want to approach it in a purely humorous way. The hairstyles and styles that might seem excessive now were cool back then. I wore my hair and clothes like that too," he said.
Hyun-woo once enjoyed a glamorous peak but now lives as a lesser-known broadcaster. Although Kang has maintained his status as a top star, he understands the feeling of being forgotten. He has carried the thought of potentially being forgotten since his debut.
"I’ve always been on an upward trajectory, but I’ve fluctuated within that. However, I don’t think I’ve ever fallen below the 2012 average. I might have fluctuated around the 50-day average. Ha ha. I’ve always thought about being forgotten since my debut. I felt that way since 'The Temptation of Wolves' did well. I’ve always thought I would eventually be forgotten. I’ve lasted longer than I expected, but someday I will be forgotten. There will come a time when my work decreases, and as a person, I will eventually be forgotten too. People will think, 'Was there someone like that?'">
Kang is now considering projects beyond South Korea. However, he is no longer waiting for someone to recognize him and cast him. He has shifted towards creating and taking initiative in his work.
"In the past, I hoped someone would want to work with me, recognize me, and cast me. But now I think, 'Forget it. I’ll just create it myself.' It doesn’t have to be limited to Korea. To put it simply, I want to work with truly talented people from around the world."
