In 2008, Kang became one of the "models" in Jump Shoe's print ad campaign. He also appears in commercials for the product.
In 2003, Kang starred in the student film 9:30. The film is included as part of the "Special Features" on the DVD release of Undoing, which he also stars in.
Sung has been a producer for a number of movies he has starred in. He admits that he would rather not have to produce, but believes that if he didn't, the movies would never get made. He says that if it were up to him, he'd only act.
Sung says that before he was cast as "Han" in The Fast and the Furious: Tokyo Drift he was unaware of the drifting subculture that exsists in Japan. It wasn't until he began researching for the part that he learned what a popular sport drifting actually is all over the world.
Sung is a regular at the San Diego Asian Film Festival. The event, which first took place in 2000, is sponsored by the San Diego Asian Film Foundation.
To prepare for his role in The Motel, Sung went on a diet of Burger King food at the request of director Micheal Kang. He says that the diet was 'an exercise to show that he's a guy who's lost all physical and mental control of himself.'
Kang says one of the things he dislikes most about Hollywood is the stereotypes that Asian actors are faced when being cast in a role.
When director Michael Kang was casting the part of "Sam" in The Motel, he didn't believe that Sung could play the role, thinking he was too young. Sung, however, fought for the part and soon convinced Michael to give him a chance. In the end Michael was very happy with Sung's performance.
At the age of 22 Sung joined an experimental theatre group in Los Angeles called the Friends and Artists Studio.
Sung, who is of Korean descent, jokes that he is often mistaken as being Chinese or Vietnamese.
Kang feels that acting is a scary profession considering, at times, you may never know when you are going to work again. His advice to other Asian-Americans who feel as though they must act is to always find something else to do as insurance.
Kang's first role on screen was as a hand double in a straight-to-video Yakuza movie.
Kang credits his acting teacher, Sal Romeo, for influencing him the most in his endeavors as an actor.
Sung owns a restaurant in Los Angeles, California called Saketini. They serve a mixture of Asian/European Cuisine.
Kang is 6'0½" with black hair and brown eyes.
Sung Kang: It's tough for Asian American actors, so we need all the support we can get from the Asian American community. We need you to come out and see the films, spread the word, and do whatever you can to help us, and the community overall, to raise our visibility in Hollywood and the media.
Sung Kang: (on his future as an actor) Seriously, I just want to be challenged, man. I really don't care if it's a gay, straight, white, black character, whatever. I just don't want to be a walking set piece, that's all. As an actor, I just want to keep being challenged.
Sung Kang: (on his career) I feel blessed. But at the same time, I have the same worries of last year. I'm thinking, 'What's next?' You're always looking for that next project that can provide those substantial roles.
Sung Kang: If you can find something to make you happy, really happy, go do that, because becoming an actor, even staying an actor, is really one of the hardest things to do. I mean, if you're looking for the superficial stuff, like the premieres, the glitz, which is all nice, good luck, because that stuff doesn't mean a lot and the rest is hard work. I think it's about finding what role in life is right for you. Would being an actor be right for you--will it make you happy? I was lucky that I knew that's what I wanted to do.
Sung Kang: (on playing the role of "Han" in The Fast and the Furious: Tokyo Drift) I had to do research, because I didn't grow up in OC. But tapping into angst wasn't hard for me. There's angst I have that I can tap into. Han had similar type of angst. Getting the feel of a masculine self confident man, it was difficult. My whole life, I was a second class citizen. Han is like a guy's guy. I think for us, as Asian Americans, I don't know speaking personally, it's been tough to understand to know what it means to be a sexual male, where's there's self-esteem. I grew up insecure. I had my Asian actor friends, and I stole a lot from them.
Sung Kang: I hope that my contribution as an actor can make a difference in the way we as Asian Americans are portrayed in media.
Sung Kang: (on wanting to become an actor) When I was twelve, my parents took me to San Francisco, and on the pier, there was this mime was performing; he made me laugh, cry, [be] happy. I mean, he was able to evoke all these emotions, and I thought it would be amazing to be able to do that for someone.
