So much glass was used that the crew began calling the movie "Glass Story".
Jackie Chan sustained burns on his hands during the pole slide scene in the mall. The Christmas tree lights were plugged into the wall instead of a low-voltage car battery.
The scene where the villains crash through the bus window and fall onto the ground was an accident. They were really supposed to fall onto the car, but due to the air brakes of the bus, there was a pump back, creating space between the bus and the car.
The climactic mall pole slide sequence was filmed in one take, without any rehearsals or use of wires.
Jackie Chan was hospitalized following the stunt where he flips over the balcony and crashes through the glass and light display, as he was not breathing.
