Errores

During the intro scenes, eight ninja run the parcour. When they scale the wall with their hand-claws, there are suddenly just six, and when they run down the steps in the forest, they suddenly number eight again.

In the final scene when Chee makes his remark about femininity being the best weapon, Ching and Jen Moo simultaneously execute a flying kick against him. But when Chee starts talking, both fighters are just about ten feet away from him; but their running starts come from a longer distance - at no point do they step backwards.

When Jen Moo darkens the trap room, Ching drops the last lamp into a vase to prevent it from being extinguished. But in that shot, he grabs the lamp, raises his arm, the light in his hand just winks out, and the vase suddenly lights up. A falling lamp is nowhere in sight.

When Ching employs the black-and-white sheet, in some scenes he spreads it across his back before he blends in with the walls. But he gets ready to ambush Jen Moo holding the sheet spread out on his front side without revealing himself while changing hold and position.

Leong Kit's son ties a headband around his hair before he starts his demonstration at the restaurant. In the first shot, his hair is held tight by the band, but when he starts his exercises, it suddenly overlaps the band.

When Fukuda/Uncle Foo unearths his ninja weapons cache, he pulls his katana half out of its sheath. You can easily see the glass panel sliding with the handguard to make the blade gleam in the light.

Jen Moo cuts off the God Skills monk's ear, but as Ching picks it up, it strangely shows no opening for the ear canal.
