Illumination released the official teaser trailer for "Not Alone," an upcoming animated film starring Timothée Chalamet and Selena Gomez.

The project marks a strategic expansion for Illumination as it blends science fiction and romance to attract a broader audience. By pairing two high-profile stars for the voice roles, the studio aims to generate significant anticipation ahead of the film's premiere.

Timothée Chalamet provides the voice for the character Joe, while Selena Gomez voices Fran [1]. The teaser trailer, which runs for nearly three minutes [2], offers a first look at the story and characters within an alien-filled setting [3].

Distributed by Universal Pictures, the film has been described across various reports as a sci-fi romance [4], an animated adventure [5], and an animated rom-com [6]. The footage previews a world populated by adorable aliens and explores the dynamic between the two lead characters.

The studio has scheduled "Not Alone" to open in theaters in April 2027 [7]. This release window places the film in a prime slot for spring audiences, a period often used by major studios for family-oriented and animated features.

Illumination continues to build its portfolio of original animated intellectual properties. This latest teaser serves as the primary promotional tool to introduce the visual style and narrative tone of the production to a global audience [3].

“Timothée Chalamet provides the voice for the character Joe, while Selena Gomez voices Fran.”

The casting of Chalamet and Gomez suggests that Illumination is pivoting toward a 'four-quadrant' appeal, targeting both children and young adults. By diversifying its genre output into sci-fi romance, the studio is attempting to move beyond the slapstick comedy formula that defined its earlier successes.
