Dawson Casting: For a good reason. If Elizabeth Shue actually was 17 when this was made, the whole "looking-like-the-Playboy-centerfold" thing would have crossed the line.
Also, Bradley Whitford was 27 when he played Chris's boyfriend in this film.
Real-Life Relative: Elisabeth Shue's brother, Andrew Shue, has a role as an extra at the frat party. He is at the bar laughing at Daryl.
Recycled: The Series: A sitcom pilot for a TV version aired on CBS but did not go to series. The most notable actors to appear in the pilot were Joey Lawrence and Brian Austin Green as Brad and Daryl. The premise centered on Chris, Brenda, and the kids getting held up at a store, locked in a storage room, and then trying to escape through the sewers where they come face-to-face with an alligator.
Throw It In!: During the scene where Brenda tries to buy a hot dog, the vendor improvised the line "Then I don't have a fucking weiner!" The director thought it was hilarious, but the executives told him to take it out of the theatrical release to keep it PG-13.
Vendor: Look, you slip me the cash, and I'll slip you the weiner.
Brenda: But I don't have any cash!
Vendor: Then I don't have a weiner!
Also the song they improvise to get off the stage.
Technology Marches On: Within a few years of this film's release, Brenda could have stocked up on cash from the bus station ATM rather than needing a ride, and Chris could've called a tow truck and cab from her cell immediately after getting a flat.
Although Vincent D'Onofrio does a good job playing Dawson/The Mighty Thor, originally the part was slated for flamboyant metal musician John Mikl Thor (as something of a Casting Gag.)
Steven Spielberg considered being the executive producer of this film and have the film released under the Amblin banner, to help his friend Chris Columbus get the directing job. However Columbus had the directing job secured.
