The Hollywood system has its own problems. Movie making is never an easy job.

I brought in two genius guys from Korea. Guys who did my favorite movies like Oldboy and The Man from Nowhere. It was fun working with them. Even though they don't speak Japanese and I don't speak Korean, I knew from day one we were speaking the same language because they love my work and I love theirs. We instantly connected. There was zero frustration.

It doesn't matter where you make movies or what the size of the movie you make is. It's a very hard job - especially director.

I don't really consider myself a horror director or a violent director at all.

Ultimately I'm making movies because of the producers and I don't want to disappoint my producer. It's always a tough balance to figure out how far I listen to them though.

Producers don't like the director who ignores their opinion - but I always try not to be the nicest person when making a movie. It's easy to do that. Just say 'Yes sir', "Alright', 'Okay' - but they're not seeing the movie because if they can, they should be directing the movie.

I believe Korea is making the best movies. Only in Korea - you can do whatever you want to without any rating system or whatever. They can make world-class karate movies and make lots of money, which is very important.
