Kelly LeBrock Threatened To 'Kick His Ass' After Her 15-Year-Old Weird Science Co-Star Went Off Script During Kissing Scene

One thing about 1980s Hollywood: absolutely nobody was operating under modern workplace guidelines.

An old Kelly LeBrock interview has started making the rounds online again after fans rediscovered her behind-the-scenes story from Weird Science, in which her teenage co-star, Ilan Mitchell-Smith, apparently improvised during one of their kissing scenes.

According to LeBrock, the scene in John Hughes’ 1985 cult comedy was supposed to be a standard on-camera kiss between her character Lisa and Mitchell-Smith’s awkward teenage character Wyatt. Instead, the then-15-year-old actor allegedly turned it into a French kiss mid-scene.

LeBrock later recalled the moment by saying, “Every hair on the back of my spine went up.”

Which is about as clear of a “what the hell was that?” reaction as you can possibly get.

The second director John Hughes called “cut,” LeBrock immediately confronted him.

“If you ever do that again, I’m going to kick your ass!”

Honestly? Fair response.

The story has exploded online again because the actual scene is now circulating alongside the interview clip, giving people modern-day whiplash as they revisit a movie already deeply rooted in peak 1980s chaos. The film itself starred Anthony Michael Hall and Ilan Mitchell-Smith as two teenage nerds who literally create the “perfect woman” on a computer, with LeBrock playing the fantasy brought to life.

At the time of filming, LeBrock was in her mid-20s while Mitchell-Smith was still a teenager. Mitchell-Smith himself later admitted in interviews that filming romantic scenes with LeBrock felt “weird in all kinds of ways,” noting that the fantasy people imagined about the situation didn’t really match reality on set.

That hasn’t stopped the internet from having wildly divided reactions to the resurfaced story.

Some people are looking back at Weird Science through a modern lens and realizing just how insane a lot of 1980s teen comedies actually were. Others are mostly stunned by the sheer confidence of a 15-year-old actor deciding to go rogue in a kissing scene with one of the biggest sex symbols of the decade.

And then there’s the third group of people simply shrugging and saying, “Yeah, that sounds exactly like an 80s movie set.”

Which… honestly… also fair.

Because Weird Science was never exactly subtle. Even back in 1985, mainstream reviews were pointing out how bizarre and over-the-top the movie’s premise was, with critics describing the film as a fantasy about teenage boys creating their ideal woman.

Still, the funniest part of the entire story might be how direct LeBrock handled it. No passive-aggressive Hollywood diplomacy. No vague actor-speak. Just immediate “do that again and I’ll kick your ass” energy.

A conflict resolution strategy that probably worked pretty effectively in 1985.
