9 Movie Plot Holes Confirmed By The Creators
7. DNA Evidence Would've Solved Everything - Basic Instinct
The Plot Hole
Paul Verhoeven's legendarily smutty 1992 erotic thriller revolves around Catherine Tramell (Sharon Stone), a serial killer with a knack for slaughtering her lovers mid-coitus.
And yet, despite DNA testing being routinely deployed in crime scenes since almost a decade before the movie's release, there's not even a whisper of it during the investigations of Tramell's murders.
Had the cops simply asked for a DNA sample from Tramell, she would've been easily linked to the opening murder of rocky Johnny Boz (Bill Cable), given her intimate involvement with Boz at the time of the killing. Done and dusted.
The Confirmation
Screenwriter Joe Eszterhas actually wrote the movie in the early 1980s, back when DNA wasn't yet a prominent part of criminal investigations, and he later admitted that not doing so resulted in a major plot hole.
