Audio problem: When Axel is in the shed in the final shoot-out with Dent and Karla, there is a flopping sound from the ceiling fan. The instant Karla gets shot, the sound disappears.
Continuity mistake: At the beginning, before Karla's robbery of the jewelry store, when the limo turns the corner the front license plate reads "Dent". However, when the limo parks in front of Adriano's its front license plate reads "77".(00:00:25)
Axel Foley: Well, sir, you have 25 unpaid parking tickets and it's your car, so we have to take you in. Sidney Bernstein: Wait a second, I've got an idea. Is there something that I have, in this office, that I could hand to you and that would, make you...kinda forget that you're holding those, uh, little pink tickets there? Axel: What are you trying to say, sir? Sidney: Like, you'd be holding something in that hand, and this hand you'd forget about. This hand you'd be concentrating on. That hand you'd go, what, what did I have there? I don't even remember. Axel: What, you mean, like, if I had um... $200 in this hand? Sidney: Ouch! Let go of my arm. $200? Ouch! Please, I'm robbing you. That's what I'm doing. Here's one, here's two. They're real crisp.
Trivia: The black valet who receives Axel Foley and Billy Rosewood in the cement truck in front of the playboy mansion is played by a very young Chris Rock (by some declared to be the Eddie Murphy of our day).
