Then/Now: The Cast of 'Weird Science'

John Hughes twisted "Frankenstein" into a movie about teenage boys in this 1985 comedy. Nerd BFFs Wyatt (Ilan Mitchell-Smith) and Gary (Anthony Michael Hall) create their dream girl with the help of a computer (this seemed plausible in the 80s), and all heck breaks loose. But what are the "Weird Science" kids up to, 25 years later? Click through to find out. (Warner Bros.) (-)

“So what would you little maniacs like to do first?” Kelly LeBrock's "Lisa" introduced her socially-challenged creators to the wonders of underage drinking, bikers, and babes.

After directing teen classics like "Sixteen Candles" and "The Breakfast Club," the late John Hughes brought us the hit flick "Weird Science." At left, Wyatt and Wally prepare to create their dream girl.

Nerdy roles in John Hughes movies “Sixteen Candles”and “The Breakfast Club” made Hall an 80s star, and a member of Hollywood’s Brat Pack. He played to type in “Weird Science,” starring as 15 year-old nerd Gary Wallace, who creates a woman with his BFF Wyatt (Ilan Mitchell-Smith). (Warner Bros.)

After “Weird Science,” Hall, then 17, joined the cast of “Saturday Night Live” in order to shed his loveable nerd typecasting. Movies that followed include “Johnny Be Good,” “Edward Scissorhands,” “Six Degrees of Separation” and “Pirates of Silicon Valley.” The actor released an album with his band, Hall of Mirrors, in 1999.  Now 42, Hall starred in the series “The Dead Zone” from 2002 to 2007 and played the Gotham City television news anchor Mike Engel in "The Dark Knight." He is currently taking guest spots on TV series, including recent appearances on “Community” and “CSI: Miami.” (REUTERS)

After her debut in 1984's "The Woman in Red," 80s hottie LeBrock was cast as computer-generated Lisa, who possesses the looks of a model, the intelligence of Albert Einstein, the fashion sense of David Lee Roth, plus super powers like teleportation and time manipulation. (Warner Bros.)  

LeBrock married Steven Seagal in 1987 and co-starred in "Hard to Kill" with him. The actrress appeared in several movies throughout the 90s, but took time off to raise her children. In 1996, LeBrock divorced Seagal and appeared in a few more flicks (like "Zerophilia"). In recent years, the actress, now 50, competed on reality shows "Celebrity Fit Club" and "Hell's Kitchen" (the UK version). (REUTERS)

Sadly, "Weird Science" was Ilan's only big movie. He went on to do a couple of other 80s flicks, including "The Chocolate War, " but his last acting gig was a 1991 episode of "Silk Stalkings." Mitchell-Smith, 40, has left Hollywood for academia; He's now an English professor at California State University Long Beach. He is married with two children.
