Jesse Plemons in the movie “Bugonia.”

Jesse Plemons is never one to chew scenery. Even when handed a role that edges on madness, he doesn’t go big. Instead, he goes deep, building tension quietly from the inside out. And in Yorgos Lanthimos’ uncategorizable, darkly comic sci-fi thriller, Plemons — reuniting with the director after playing three characters in last year’s “Kinds of Kindness” — delivers one of his most riveting performances yet. As Teddy, a rumpled, reclusive beekeeper convinced that a pharma CEO (Emma Stone) is an alien from the planet Andromeda, Plemons channels paranoia, grief and righteousness into something both absurd and unnervingly sincere. The “I do my own research” archetype could easily veer into “SNL” sketch territory but he plays it heartbreakingly straight, creating a chillingly familiar portrait of a man lost in an algorithmic maze of internet rabbit holes and desperate for clarity in a world that no longer makes sense. Teddy enlists his younger cousin Don (Aidan Delbis, an autistic first-time actor in a mesmerizing turn) to help him abduct Stone’s steely executive, drawing him into the mission in a misguided effort to protect him. Even as things spiral into chaos, Plemons (a 2022 supporting actor Oscar nominee for Jane Campion’s “The Power of the Dog”) roots the performance in a warped but recognizably human emotional logic. The result captures the anxious, conspiratorial spirit of 2025 with eerie precision, proving once again that Plemons doesn’t need to raise his voice to deliver a performance that speaks volumes. — Josh Rottenberg
