Chalamet Joins Illumination's 'Not Alone'

Timothee Chalamet will voice an introverted rocket mechanic opposite Selena Gomez in Illumination's alien comedy 'Not Alone,' marking his animation debut.

Chalamet Steps Into the Recording Booth

Timothee Chalamet is trying something he has never done before: lending his voice to an animated character. As reported by Variety, the actor has signed on to play Joe, described as an "introverted rocket mechanic who lives a quiet life alone," in Illumination's forthcoming feature Not Alone. For an actor whose recent filmography leans heavily toward prestige cinema, the move represents a fresh creative direction and his first proper foray into family animation.

The casting continues a remarkable stretch for Chalamet, who has spent the past several years collecting some of the most talked-about roles in Hollywood)), from the desert epics of Dune to the awards-circuit drama Marty Supreme. Stepping behind a microphone for a comedy aimed at all ages is a deliberate change of pace, and one that keeps him visible to a broad new audience.

An Unlikely Love Story Among the Stars

According to Variety, Chalamet shares the screen with Selena Gomez, who voices Fran, a "brilliant astro-botanist" working to build the world's first plant-fueled rocket. The premise leans into both romance and chaos: as Joe and Fran ready their machine for launch, an attraction blooms between them. Their plans are upended when three small aliens in search of refuge hijack the ship in a bid to make their own way home.

The setup gives the film room for the kind of broad, character-driven comedy Illumination has built its reputation on, balancing heartfelt moments between its two leads with the slapstick energy of its extraterrestrial stowaways.

The Creative Team and Voice Cast

Variety reports that Not Alone is being produced by Illumination founder and chief executive Chris Meledandri, whose studio is responsible for the Despicable Me and Minions juggernauts as well as the record-breaking The Super Mario Bros. Movie. The film is being directed jointly by Eric Guillon, Claire Dodgson and Jonathan Del Val.

Beyond its two headliners, the project has assembled a deep bench of comedic talent. The supporting voice cast, per Variety, includes:

Rob Brydon, Diane Morgan and Jamie Demetriou as the trio of aliens
Brett Goldstein as Officer Zandro
Allison Janney and Lamorne Morris in additional roles

That lineup blends British comedy mainstays with familiar American faces, suggesting a film built to land jokes for viewers on both sides of the Atlantic.

What It Means and What Comes Next

Variety notes that Not Alone is scheduled to reach theaters on April 16, 2027. The announcement arrived during a particularly active period for Chalamet, who recently teased a "new movie announcement" on his Instagram Stories and is widely anticipated to reprise his role as Paul Atreides in Dune: Part Three later this year.

For Illumination, pairing two performers with massive online followings offers an obvious marketing advantage long before opening weekend. For Chalamet, the part is a calculated pivot, swapping intense dramatic fare for accessible, all-audiences comedy without ceding any of his spotlight. The studio's track record with broad commercial hits raises expectations, but with the release nearly a year out, there is little to judge yet beyond the casting itself, which has already set fans of both stars talking.
