Timothée Chalamet and Selena Gomez to Voice Star in Universal and Illumination’s ‘Not Alone,’ Chalamet Teases at Annecy

Universal Pictures and Illumination are moving forward with an animated feature titled “Not Alone,” with Timothée Chalamet and Selena Gomez set to voice star, according to a report published June 22, 2026. The casting news surfaced amid festival coverage tied to the Annecy International Animation Film Festival, where “Not Alone” was expected to be highlighted as part of the film’s early rollout.

Chalamet, who is credited in the report as teasing a “new movie announcement,” shared the information through an Instagram story over the weekend, before the broader news became public through coverage connected to Annecy. The timing places the announcement inside the festival period, when industry executives, press, and animation creators typically share projects, schedules, and promotional details.

The Hollywood Reporter reported that Chalamet and Gomez will both lend their voices to the film. The report frames the announcement as part of a wider set of items emerging from Annecy, an event known for showcasing animation in development and in production, along with updates from major studios and creative talent.

Universal and Illumination are the credited production and distribution partners named in the report. As is typical for major studio animated releases, casting announcements are often used to report tone, target audience, and marketing momentum ahead of additional details such as character descriptions, supporting voice cast, and release timing.

While the report confirms the two headlining voice performances and the film title, it does not provide additional specifics in the supplied material about the plot, the characters they will portray, or the production timeline. Those details are expected to follow through additional announcements tied to the festival or later studio updates.

The “Not Alone” announcement illustrates how studios increasingly use both festival visibility and social media to set expectations for early audiences and industry stakeholders. By tying the casting reveal to a public-facing teaser on Instagram and festival coverage from Annecy, Universal and Illumination can reach entertainment press immediately while maintaining momentum in the crowded animation calendar.

Next steps for viewers and industry observers will likely include confirmation of character roles, additional cast and crew, and any release-window information as Universal and Illumination continue their promotional schedule. More information may also emerge from Annecy programming announcements and related festival industry events.
