In order to appear in ‘Weird Science,’ Anthony Michael Hall chose not to return to his role as Rusty Griswold in 'National Lampoon’s European Vacation.'

In the film, dweebs Gary Wallace and Wyatt Donnelly bring Lisa to life by connecting a doll to a government computer and waiting for a thunderstorm. Ouch.

Instead of asking an onslaught of existential questions, pondering humanity, and, well, running far, far away after being animated into a human from a doll, Lisa decides to conjure a pink Cadillac convertible and take Gary and Wyatt to get fake IDs.

Even though Vernon Wells appeared in 'Weird Science' as Wes, his 'Mad Max 2: The Road Warrior' character, his role is listed as 'Lord General.'

Kelly LeBrock may have stolen the show as Lisa, however the role was originally supposed to go to Sports Illustrated swimsuit model Kelly Emberg. She left the project after just two days, citing creative differences.

While never directly addressed in the film, ‘Weird Science’ takes place at the fictitious ‘Shermer High School.’ If that name sounds familiar, it’s because the school is also featured in Hughes' 1985 classic, ‘The Breakfast Club.’

Despite its title and bonkers plot, some critics argued that 'Weird Science' wasn’t weird enough. “'Weird Science' is not nearly as weird as it should have been, and, in fact, is a rather conventional kids-in-heat film, and a chaste one at that,” Variety wrote in their review of the flick. “Director-writer John Hughes squanders the opportunity to comment on the power struggle between the sexes for a few easy laughs."

Two years after starring in the iconic flick, model Kelly LeBrock tied the knot with Steven Seagal. The pair remained married until 1996.

Though Universal Studios planned on making a raunchier reboot of the iconic film as early as 2013, the project never came to pass.

Even with these apparent delays, some of the original cast were seemingly on board with a reboot. Back in 2017, Ilan Mitchell-Smith revealed he'd be open to revisiting the story ... with a special guest in mind. “My favorite idea for a 'Weird Science 2' would be in one in which Wyatt and Gary are all grown up and they have daughters — daughters who find their old stuff,” the star told Hollywood Life. “They get together and make Channing Tatum."
