When news came out that Jackie Chan and Super Junior's Siwon would be starring on 'Running Man', viewers knew that it's one episode they wouldn't miss out on.

Jackie Chan, who visited Korea to promote his film 'Chinese Zodiac', fooled the cast members by appearing only on video at first, pretending to give them a mission like he's done on a previous episode. However, he suddenly appeared in person, surprising every 'Running Man' member and sending them into a hyper frenzy. Jackie Chan spoke fluent Korean and enjoyed every mission he was given, even showing a cute side with his toesocks.

Siwon also played a crucial role in the final race.

You can see the action for yourself on March 3rd at 6:10PM KST on SBS!
