Actor Lee Byung Hun, currently a hot commodity in both Korea and abroad, recently talked about his experiences while filming for the upcoming Hollywood blockbuster film, 'RED 2'. The film is a sequel to the original "RED", which was released in 2010 and featured a star studded cast including John Malkovich and Bruce Willis.

"In my first appearance in 'RED 2', I go through a full body check. They're checking me for weapons, and I have to really strip down," he said. "I was okay about stripping down, but in the screenplay, there was this one line describing a 'perfect body'. So I figured that I would have to work very hard for about three months just for that one line."

Although Lee Byung Hun is already well-known for his chiseled body, he doesn't always take care of his muscles, he said. "I only exercise hard when my character requires a muscular body," he said. "It's actually a very tiring and exhausting part. Not only do I have to work out, but I have to check my eating habits as well. I'm not even a professional athlete, so I don't only focus on working out."

"Once you build muscles once, it's not hard to build them up again," he advised. "They say that the muscles remember. But now, it's getting harder because of my age. Once you get past a certain number, it's medically much harder to form muscles in the first place," he laughed.

'RED 2' is scheduled for release in August of 2013.
