Timothée Chalamet and Selena Gomez team up for alien animation.

Making his animation debut, the Wonka star will lend his voice to rocket mechanic Joe in the film titled Not Alone. Universal Pictures has also revealed Gomez will voice the character of a scientist called Fran. Joe is described as an "introverted rocket mechanic who lives a quiet life alone", while Fran is a "brilliant astro-botanist who is developing the world's first-ever plant-fuelled rocket." Not Alone is the latest film from Illumination, the studio which has racked up hits including the Despicable Me franchise and Super Mario Bros.
