Zatoichi (2003)

Revealing mistake: When the Bodyguard attacks the rival gang, he stabs one of the torch carriers, to which we get a close-up of. As the blade goes in, blood comes out - when the Bodyguard removes his blade, there is no stab wound, not even in the torch carriers clothes.

Revealing mistake: At his first attack, the sword of the bad samurai is a computer generated image. You can see it, because it is waggling unnaturally although the samurai holds it still.

Shinkichi: Aren't you betting?
Zatôichi: I'll just watch for now.
Shinkichi: Watch? But you're blind.

Shinkichi: I have to say, it's incredible. You really look like a woman! Does make-up make men beautiful?
Geisha Seitaro 'Osei' Naruto: It doesn't work on everyone. It depends on the face.

Shinkichi: Massuer, did you see that?
Zatôichi: I don't see much.
