Jackie Chan will be appearing on 'Running Man'!

The superstar previously made an�appearance�on the show back in 2011. Back then, he appeared on the screen for just a brief moment, but this time he will be actually joining the 'Running Man' crew with Siwon to fulfill a mission.

He's currently in Korea to promote 'Chinese Zodiac' with co-star Kwon Sang Woo, and he'll even be appearing on 'Knee Drop Guru'.

Jackie Chan began filming for 'Running Man' with Siwon on the 19th in Seoul. A 'Running Man' staff member stated, "He never lost his smile while he was filming. He promised to treat the members if they came to China."

Siwon was grateful to be filming with such a legend as he took to his Twitter to write,
