Corrected entry: 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 definitely too long to fit in the bag or under the suit, and I've never heard of dismantable combat swords.
Revenge of the Ninja (1983)
1 corrected entry
Directed by: Sam Firstenberg
Starring: Sho Kosugi, Keith Vitali, Arthur Roberts, Virgil Frye
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.
Cho Osaki: Only a ninja can stop a ninja.
Trivia: It is commonplace for Sho Kosugi films that whenever a family is to be portrayed; his two sons Shane and Kane are cast into corresponding roles.
Correction: There are such things as collapsible swords.
