Talk about practice makes perfect. Look up that phrase in the dictionary, and you’ll probably find a picture of Jackie Chan.
I liked the part about how a similar stunt/scene works better in some of the movies made in Hong Kong because the directors there give him longer to practice and do the scene over and over again until he’s satisfied.
And this, towards the end:
“He doesn’t win because he’s a better fighter. He wins because he doesn’t give up.”
