I want to challenge myself to see where my limit is and experiment with a lot of different films. A lot of artists from Asia focus too much on their Asian background. I don't want to let go of my background, but to be a success in the U.S., which is my goal, I realize I need to surround myself with American filmmakers and producers.

The biggest competition is myself. I am not looking to follow others or pull them down. I'm planning to test my own boundaries.

I'd love to continue my career in Hollywood - I'd love to do another action film, or a romantic comedy, or horror. I love horror films.

In Korea, when I started, there wasn't a trend where people chose to be both actors and singers. I was the first to do both. It was a great deal hard work, but I got a lot of support and love from my audience. And for me to receive the same treatment overseas, I felt that I was also very lucky.
