The Trailer
Press play: the Mare's Nest trailer
Dropped September 29, 2025
What we know
Mare's Nest (2026)
Moon travels through a mysterious unexplained world free of adults. Moon meets a scholar turned sage and her translator in a mountain hut, where she tries to understand what is happening, based on a play by Don DeLillo. She meets many others who perform for her, show her a film, give her gifts, show her different possibilities for living. She observes and moves on into an unknown future.
The same weekend also brings Supergirl. Two trailers, one argument about which one wins the window.
Mare's Nest opens in theaters on June 24, 2026.

By opening weekend everyone will have a take. The reactions that matter are the ones recorded before the takes calcify.
