Beverly Hills Ninja (1997)

Continuity mistake: When Chris Farley has Chris Rock drive him around blindfolded they get themselves onto a horse racetrack. While they are driving around the track you can see the tire tracks left by the camera car in front of them.

Trivia: When Haru is about to get arrested (right before the ninja dude throws that little ball and takes his place), the stocky and balding cop all they way to the left (or right?) is Kevin Farley, Chris's brother.
