It Happened One Night (1934)

Continuity mistake: The scarf around Ellie's neck (in the car) repeatedly changes. Make up your mind, love.

Continuity mistake: When the bus is about to pull out of the station Ellie places her suitcase on the overhead rack, and in the next exterior shot we see the license plates at the front of the bus, then it cuts to a closeup and one of the plates has changed from "F8274" to "G8278." (00:08:40)

Continuity mistake: While Ellie is standing behind the first bus (#204) when it's filling up on gas at the rest stop her suitcase is stolen, and as Peter starts chasing after the thief note all the license plate numbers including "173-909" and "G8271" at the back of the bus. Later, when Ellie and Peter are on the second bus (#217) as it drives into the muddy ditch, in the closeup we see license plate numbers "173-909" and "G8271" (and more) which are the same as the first bus they were on. (00:08:40 - 00:46:40)

Peter Warne: I never did like the idea of sitting on newspapers. I did it once, and all the headlines came off on my white pants. On the level! It actually happened. Nobody bought a paper that day. They just followed me around over town and read the news on the seat of my pants.

Oscar Shapeley: Believe you me.
Ellie Andrews: Believe you me, you bore me to distraction.

Ellie Andrews: I'll stop a car, and I won't use my thumb.
Peter Warne: What're you gonna do?
Ellie Andrews: It's a system all my own.
