Singer-turned-actor Lee Seung Gi surprised the fans by transforming into a fighter in his latest stills for upcoming MBC drama ‘Book of the House of Gu’.

Portraying the outgoing and reckless half-man-half-beast Choi Kang Chi, Lee Seung Gi filmed his first action scene armed with punches and high kicks. It was also revealed that the actor filmed the scenes for eight hours straight but didn′t show any sign of exhaustion.

Lee Seung Gi said, “I prepared everything from the basics because the drama will have intense action scenes. This is my first historical drama and action role so I’m looking forward to the action scenes up ahead.”

The drama will premiere through MBC beginning on April 8 KST.
