Johnny Mnemonic (1995)
Keanu Reeves plays "the ultimate hard drive" – a courier who uses his brain to store corporate data packages. Only trouble is, he's taken on more than he can handle on his latest job, and risks psychological damage, or even death.
Based on a short story by William Gibson, founding father of cyberpunk, how could this sci-fi actioner fail? Well, when the studio heavily recut it just before release, it doomed the film to mediocre reviews and a cult following. Losing the heroin-addicted dolphin was a mistake, it turns out.
