A symbol of Hong Kong action films, Jackie Chan is never short of death-defying stories. And in his latest film, Railroad Tigers, the 62-year-old kung fu giant again tests his limits: He gets onto a moving train to combat his enemies.

The scenes are shot in a frigid location in northeastern China where the temperatures are minus 20 C.

To create spectacular visual effects, two gigantic fans are used to blow at the actors, making their hair and collars move like they are traveling really fast. But in reality they are moving at around 20 miles an hour.
