Beverly Hills Ninja (1997)

Continuity mistake: When Chris Farley is pretending to be a Chinese cook at that one restaurant, cooking, the brown spot on the stove keeps on changing size.

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.
