Universal Pictures and Illumination announce the animated alien-themed film “Not Alone,” with Timothée Chalamet and Selena Gomez set to provide voice performances. The project is revealed at the Annecy International Animation Film Festival in France, and Chalamet previously hinted at a forthcoming announcement on social media. Chalamet is scheduled to voice Joe, described as an introverted rocket mechanic who lives a quiet life alone. Gomez will voice Fran, a brilliant astro-botanist developing an invention tied to space travel, as described in the studios’ materials. The film is planned for a wide release on April 16, 2027. Other cast members mentioned across the coverage include Brett Goldstein, Allison Janney, and Lamorne Morris. The announcement indicates that “Not Alone” is part of Universal’s Illumination slate and will replace an earlier “Untitled Illumination Event Film” in the same release slot. The outlets present the same core details about the film’s premise, principal voice cast, and release timing, with differences mainly in how the cast and plot elements are introduced.
