( CNN ) -- With over 20 years as an actor , Lee Byung-hun has a gained a serious on-screen persona . But when the camera is off , the 39-year-old South Korean is more joker than brooding artist . Sienna Miller , his co-star in the 2009 blockbuster `` G.I . Joe : The Rise of Cobra '' -- Lee 's first foray into Hollywood -- described Lee as not only incredibly talented and handsome , but also incredibly funny and silly . It 's perhaps an unexpected accolade for the star of films like `` Joint Security Area '' and `` The Good , the Bad , The Weird . '' Yet he admits that while he takes his work seriously , in `` real life '' he likes nothing more than having fun and relaxing with a bottle of wine . For a bit of respite from the fame and adulation he faces daily in South Korea , and for a bit of fun , Lee once became a taxi driver for a few days . `` No one recognized me . It was a weird experience , '' he told CNN . After returning the taxi back to a friend and playing with being anonymous , Lee was back into his real life , starring in hugely popular South Korean TV series and making a name for himself in Hollywood . `` Even a few years ago no one thought it would happen . It was just a dream for Korean actors , '' he said . With `` G.I . Joe '' sequels to come , he could soon be hiding from an even bigger army of fans .
South Korean actor is star of many acclaimed Korean films . Appeared in 2009 Hollywood film `` G.I . Joe : The Movie ', which was a huge hit and won the Best Picture Oscar for 2010. Has been star of South Korean soap operas and TV series for around 20 years .
