The 10 Best Paranoid Movies Full of Fear and Uncertainty, Ranked by Whatnerd

"Back in 1961, Joseph Heller summarized the crux of paranoia in his seminal novel Catch-22 with one incredible sentence: 'Just because you're paranoid doesn't mean they aren't after you.' Paranoia is uncertainty manifest. As you begin to suspect your neighbors, your co-workers, your significant other, or even your very grasp on reality, the truth grows increasingly murky and dangerous. This sneaking suspicion can be terrifying, nauseating, paralyzing, or claustrophobic. Unsurprisingly, a few storytellers have made good use of this unsettling sensation by making great movies about it. Here are the best movies where paranoia is palpable, where there's a creeping sense of dread that no one can be trusted, where fear and uncertainty cause characters to distrust everything." - whatnerd.com
