Weird Science is a 1985 American teen comedy written and directed by John Hughes and starring Anthony Michael Hall, Ilan Mitchell-Smith, and Kelly LeBrock.
Two high school nerds. Gary Wallace and Wyatt Donnelly decide to create a virtual and perfect woman on their home computer. They design their perfect woman by filling their computer with various forms of data and images. A lightning bolt strikes their house leading to a series of supernatural occurrences. There’s a violent explosion and when the smoke clears a beautiful woman (Kelly LeBrock) emerges from Wyatt’s bathroom.
An awesome film from the late and great John Hughes.
