According to IMDB, the female lead was Deborah Foreman, and the girl with the bosoms was Elizabeth Daily. It’s funny that Nicholas Cage was the breakout star from that. I was the target audience, high-school junior in 1983, and I didn’t think he was cute at all. Still don’t.
That’s them. DF also did Real Genius with Val Kilmer. She was the Idiot teacher’s co-ed groupie/girlfriend...then she quit I guess.
She was not a ‘great’ actress, but decent enough.
