Child's Play 2 (1990)

Continuity mistake: In one scene, Chucky and a girl are driving down a road when they get pulled over by a cop. The cop is surprised to see a "Good Guys" doll, and is shocked to see that its nose is bleeding. They do a close up of Chucky's nose, and blood is running from it. When they cut to the cops point of view, where Chucky and the girl are both in frame, the blood is gone. It doesn't reappear for the rest of that scene, even though no one wiped it away. (00:54:55)

Chucky: You little shit. Do you realise what you've done? It's too late. I've spent to much time in this body. I'm fucking trapped in here!

Trivia: Even though he offered to return to work on the film, the studio forced series creator Don Mancini to submit a script for approval while several other writers also wrote their own drafts, with no guarantee his script would be used. Thankfully, Mancini's script was chosen, and he's since written every single entry in the series.
