Revenge of the Ninja (1983)

Continuity mistake: Just before Cho kills Braden in the final fight, they use ninja-to (swords), but then suddenly the scene jumps to the swords lying on the ground and Braden using a dagger, which Cho drives into its wielder's belly.

Continuity mistake: When Braden sets out to kill Caifano's brother, he wears a business suit and carries a small bag as he enters the restrooms. But when he confronts his victim, he carries a ninja-to (ninja sword) in his sash. The sword is definetly too long to fit in the bag or under the suit, and I've never heard of dismantable combat swords.

Continuity mistake: The Masked Ninja (Braden) carries a lot of weapons which keep appearing and disappearing whilst he inflitrates Chifano's building; his spear-stick and a throwing axe (both relatively big - and therefore visible - weapons), for example, are both there whenever he needs them.

Continuity mistake: When Braden is confronted by Cho's mother, she throws a blade at him, which he catches and throws back, sticking it in her shoulder. She uses a blowgun and there are two shots of her with the blade in her shoulder and blood on her clothes from the wound. However, when she misses there is a shot of her using a smoke ball where there is nothing in her shoulder, nor is there any blood on her clothes.

Continuity mistake: When Cho is fighting Braden and falls from the roof top he stops using a hook. When he steps on the top again besides him is the exit door, but when he makes a step forward he is now inside the concrete square.

Continuity mistake: When Dave dies Cho is beside him squatting, but in the next shot he is standing up.

Continuity mistake: After Kane saves Cathy from the jacuzzi they call the police, but Cathy could not dry herself in just a few moments.

Continuity mistake: After Braden kills Cho's mother, Kane sees him from the roof and he puts his hood and mask on with no time to do it, just in a few seconds.

Continuity mistake: Before Cho and Dave confront the thugs in the park, the gray sweater of Dave is unzipped then zipped and back again between shots.

Continuity mistake: In the scene when Cho and Dave confront the thugs in the park, the guy in jeans and boots is lying on the table, but he moves between shots in several times.

Continuity mistake: When Cho is fighting the Indian on the street he cuts his chest with an axe and the sweater gets a stain of blood which disappears in the next shot.

Continuity mistake: When the Indian and the others are getting away on the van and Cho is holding onto the roof the sun changes between shots.

Continuity mistake: When Cho is explaining to the cop about the shuriken star his friend Dave is on the left side, but before he grabs the falling cup he is behind Cho.

Continuity mistake: When the group of ninjas kills Cho's family one of them cuts the throat of a woman in white, and the amount of blood of that wound changes in few shots later.

Continuity mistake: When Cho is fighting the ninjas in his house in Japan, the sun on the wood floor changes between shots.

Continuity mistake: When Kane breaks the dolls its head moves between shots.

Continuity mistake: After his fight with the Indian and the others Cho gets some wounds on his face which disappear later at the funeral of his grandmother.

Continuity mistake: The throwing stars which Braden uses to kill the one-eyed informant change from the time he throws them to the time they hit the guy. When Caifano picks up the body of the one-eyed informant, his right eye is bulging out. But after he says, "What the s**t is this?" his eye is back to normal formation. (00:26:35)

Continuity mistake: In the scene when Cho & Dave Hatcher confront the thugs in the park, the black thug is on the right, at the back, holding a radio. He says, "Oh look, here come the policemen. I wonder what they want with us this time?" In the next shot, the radio is on the park bench, in front of his knees. (00:51:25)
