Before watching the movie:
I know there must be a whole range of movies about applying martial arts to unusual activities, but I can’t come up with any others off the top of my head. Jackie Chan has probably made five of them. Maybe the training sequence in The Karate Kid counts?
This is maybe one of the highest-profile ones. I dimly remember being aware of its release, but it at best ranked “vaguely interesting”, which wasn’t nearly enough draw to get me to try to see it.
