In Rush Hour 2, there is a scene at the Red Dragon Casino where Jackie Chan is fighting the chinese girl with a bomb in his mouth.
After some kicks and punches Jackie get's kicked out through the window and lands on the floor on his back...
However, if you watch closely in the lower part of the screen, you can clearly see that Jackie lands on a red soft mattress, just before we get a close-up of him laying on the floor.
Since Jackie landed in the middle of the mattress, you can see the left and right side of the mattress beeing pushed up and shown in the lower part of the screen.
I clearly understand that Jackie Chan can't do that freefall and land on the floor for real, but I think that they should have had the camera pointed a bit more up, right? :o)
Enjoy, and watch closely (preferably in slow-motion), cause he lands pretty fast.
