As a kid I watched a movie that was my dads. All I remember from it was there was some kind of (potentially reluctant) hero / anti hero. He's trying to shoot an (Asian?) guy who could dodge the bullets. This guy ends up training him up (perhaps) and then this hero / anti hero has the same ability. Ability in the ninja sense I think. One of these powers was the ability to run across liquid surfaces I think.
What I'm pretty sure on:
- Western cop / hero / anti hero tries to shoot an Oriental fella who can dodge bullets
- At some point after the training he is being chased and he runs across wet concrete (or similar) whereas the bad guy falls straight in.
I have a feeling it was charles bronson or someone like that, and could have been quite b movie like.
