Illumination releases first trailer for Not Alone film

Universal Pictures and Illumination released the first teaser trailer for their upcoming animated feature, "Not Alone," on Tuesday, June 30, 2026. The sci-fi romantic comedy stars Timothée Chalamet and Selena Gomez in a story that blends a budding workplace romance with an interstellar adventure.

Chalamet, making his feature-length animation debut, voices Joe, an introverted rocket mechanic. Gomez plays Fran, a brilliant astrobotanist developing the world's first plant-fueled rocket. According to the official synopsis, the pair are brought together to prepare for the rocket's inaugural launch, where immediate romantic sparks fly, though neither character is adept at romance.

Their lives become further complicated when three tiny, unruly aliens named Dunk, Welly, and Shirm take refuge in Joe's home. The aliens are on the run from a zealous yet inept interplanetary law officer named Zandro and believe Fran's revolutionary rocket could be their ticket back to safety.

The supporting voice cast features British comedians Rob Brydon, Diane Morgan, and Jamie Demetriou as the three aliens. Brett Goldstein voices Officer Zandro, with Allison Janney and Lamorne Morris also featured in the film.
