The cult sci-fi hit Upgrade won't see a sequel or TV spin-off anytime soon, confirms director Leigh Whannell. The 2018 cyberpunk thriller, starring Logan Marshall-Green, follows a technophobe paralyzed in a tragic accident who regains control of his body with a futuristic chip implant. Praised for its gripping story and tech-infused action, Upgrade scored 88% on Rotten Tomatoes and grossed $16 million against a $5 million budget. Despite its ambiguous ending and fans clamoring for more, Whannell prefers leaving it as a "prophetic" standalone gem. Stream Upgrade on Netflix to see why it still sparks sci-fi conversations!
