Who Framed Roger Rabbit (1988)

Revealing mistake: When the weasels are at Eddie's apartment and Roger is handcuffed to Eddie, Roger runs under the bed and drags Eddie on the floor. As he pulls him you can clearly see a board with wheels under Eddie that is pulling him under the bed. (00:38:50)

R.K. Maroon: How much do you know about show business, Mr. Valiant?
Eddie Valiant: Only that there is no business like it, no business I know.
R.K. Maroon: Yeah. And there's no business more expensive. I'm 25 grand over budget on the latest Baby Herman cartoon. You've seen the rabbit blowing his lines. He can't keep his mind on his job. You know why?
Eddie Valiant: One too many refrigerators dropped on his head?
R.K. Maroon: Nah, he's a toon. You can drop anything you want on his head, he'll shake it off. But break his heart, goes to pieces just like you and me.

Trivia: When the taxi Jessica and Eddie are in hits the lamppost, she spins around and her dress shifts position. For a couple of frames on the laserdisc version her underwear vanishes, or at least it appears to. Opinion is divided as to whether it's a deliberate move by the animators or just an error in colouring. (https://www.snopes.com/fact-check/who-stripped-jessica-rabbit/). (00:18:15)

Question: Does "pattycake" also mean something sexual? We were obviously at first supposed to think Jessica and Acme had sex, but if they were, why would she say "pattycake" and why does Maroon say "You're not the first guy whose wife went pattycake on him"? Am I missing out on something?
