• Canoodling For Your Art: Jeff Conway really did give those hickeys to Stockard Channing.
  • Dawson Casting: Most blatantly with Olivia Newton-John and Stockard Channing. By the time the film came out, Channing was 34 (and actually old enough to have been in high school in 1959) and Newton-John was pushing 30. In fact, the only member of the core cast who was an actual teenager was then-19-year-old Dinah Manoff.
    • In the stage production, this is almost justified, as the entire story is a Flashback set off by the Framing Device of a high school reunion.
  • Hey, It's That Guy!: The jock that Sandy briefly dates is Lorenzo Lamas, better known to some people as Reno Raines.
