'Bugonia' trailer: Emma Stone's character is neither human nor alien

Trailer amps up paranoia and uncertainty

The trailer features Plemons forcing Stone to say what he wants to hear—while she keeps denying it.
It all plays into themes of belief, truth, and needing validation when nothing feels certain.
The back-and-forth really amps up the paranoia.

Film is based on a South Korean movie

Bugonia is written by Will Tracy and based on the 2003 South Korean movie Save the Green Planet.

Catch it in select theaters starting October 24, 2025, with a wider release on October 31.
Besides Stone and Plemons, Aidan Delbis also joins the cast.
