Revealing mistake: When the swordmaker writes "Bill" on the window, take a close look. The window has been wiped before (as happens at the end of the scene) and "re-steamed" - you can see the outlines of the wiping from earlier takes, with a clear contrast between that pane and the others.
O-Ren Ishii: As your leader, I encourage you from time to time, but always in a respectful manner, to question my logic. If you're unconvinced a particular plan of action I've chosen is the wisest, tell me so. But allow me to convince you. And I promise you, right here and now, no subject will ever be taboo. Except the subject that was just under discussion. The price you pay for bringing up either my Chinese or American heritage as a negative is: I collect your fucking head. [Holds up Boss Tanaka's head.] Just like this fucker here. Now if any of you sons of bitches got anything else to say, NOW'S THE FUCKING TIME! [Silence.] I didn't think so.
Vernita Green: I fucked you up. I fucked you up bad, I wish to God that I hadn't, but I did. Be that as it may, I know I don't deserve your mercy or forgiveness, however, I beseech you for both on behalf of my daughter.
The Bride: Bitch, you can stop right there. Just because I have no intention of killing you before the eyes of your daughter does not mean that parading her around in front of me is gonna inspire sympathy. You and I have unfinished business, and not a goddam fuckin thing you've done in the subsequent four years, including getting knocked up, is gonna change that.
