As we revealed last week, Jackie Chan and Choi Siwon will be in the next episode of Running Man! A preview video has been released that shows the ecstatic cast of Running Man (Choi Siwon included) reacting to the legendary Jackie Chan's arrival on set. Then towards the end of the preview, Jackie Chan coyly says "Saranghaeyo" and blows kisses to the camera. Check out the preview to get a taste of what to expect: It looks like this episode will have even more laughing than usual! Will you be joining the cast of Running Man as they carry out their missions with Choi Siwon and Jackie Chan?
