Deliberate mistake: When the Crazy 88 crew is coming in to attack the bride they use one of the shots twice. It is the one that shows 1 guy jump over a banister and go to the left of the screen then another guy comes directly after him and heads directly towards the camera. It happens at 1:21:49 and 1:21:53. (01:21:45)

Kill Bill: Volume 1 (2003)
1 deliberate mistake - chronological order
Directed by: Quentin Tarantino
Starring: Uma Thurman, Michael Madsen, Daryl Hannah, Lucy Liu, Vivica A. Fox, David Carradine, Julie Dreyfus
Continuity mistake: When The Bride is slashed on the upper back by O-Ren in their fight scene she collapses and lands on her back in the snow. After she gets up and the fight continues, there is no blood spot on the snow where she was lying. (01:29:55 - 01:31:10)
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.
Trivia: The tune that Elle Driver is whistling in the hospital is the theme from the movie 'Twisted Nerve' (1968)
