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.
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.
What Could Have Been: 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.)
