Continuity mistake: When John Candy and Steve Martin are travelling from Jefferson City, Missouri to St. Louis they are crossing the Mississippi River to enter downtown St. Louis. This would not have been possible unless the bus driver overshot the entire city and ended up across the river in Illinois.
Planes, Trains & Automobiles (1987)
Ending / spoiler
Directed by: John Hughes
Starring: Kevin Bacon, Steve Martin, John Candy, Michael McKean, Laila Robins
Del and Neal make it to Chicago and Neal boards a commuter train for home. While on the train, he thinks about his journey with Del and certain things he said along the way. Sensing something doesn't add up, he goes back to the train station to find Del still sitting there. Del confesses that he is in fact homeless, and Marie (his wife) passed away eight years ago. Neal brings Del home with him to spend Thanksgiving with his family. In the post-credits scene, the executive who was debating which picture to choose is actually still trying to determine that, with a Thanksgiving meal present on the table in the conference room.
Upvote valid corrections to help move entries into the corrections section.
Suggested correction: I agree with the original post. However, there could be several possibilities for this scenario: 1. Road closures, 2. Road construction, 3. Accidents, 4. Detours, and 5. Heavy "holiday traffic" could have contributed to the bus having to enter St. Louis from the east despite coming from Kansas in the west.
State Trooper: What the hell are you driving here?
Del: We had a small fire last night, but we caught it in the nick of time.
State Trooper: Do you have any idea how fast you were going?
Del: Funny enough, I was just talking to my friend about that. Our speedometer has melted and as a result it's very hard to see with any degree of accuracy exactly how fast we were going.
Trivia: In the scene after the plane lands in Wichita, Kansas, when the announcer comes over the loudspeaker look at the destination on the flight info display. It says "nowhere".
Question: Del was able to get a rental due to having Neil's card. Then, how was Neil able to get a rental card that eventually got him left in the parking lot if he didn't have a card?
Answer: He had multiple cards. He shows the burnt remains when he tries to rent a room.
