The Tomorrow War premiered on Prime Video on July 2, 2021, and while it received a mixed response from critics, it broke several viewing figures. Due to its success, talks of a possible sequel began the same month as its release. However, more than three years have passed since then and there has been no update on the matter. However, Yvonne Strahovski, who plays Colonel Muri Forester in the original film, recently questioned whether a sequel was still in development.

In a recent comment, Strahovski made it clear that she couldn't speak to the status of the sequel, before adding that she "hoped" it would still happen.

"I probably can't say anything about it, unfortunately," Strahovski told ComicBook. "I hope it works out, but that's it. That's all I have to say about it."

In the original film, Strahovski’s Muri Forester is the adult daughter of Chris Pratt’s Dan Forester. The story takes place in a future world where humanity is confronted by an alien invasion. Dan, a biology teacher and former Green Beret, travels from 2022 to 2051 to battle the aliens, known as the Whitespikes, and reunites with his daughter, whom he discovers is the leader of the human resistance.
