Currently, there is no official word on a Rambo 6 movie slated for release in 2025. The most recent film in the series was Rambo: Last Blood (2019), which was supposed to be the end of John Rambo’s journey.

Despite rumors of a sequel, Sylvester Stallone has repeatedly stated that he has no plans to reprise the role. In an interview at the Toronto International Film Festival, Stallone said, “Rambo, I can leave him behind. He’s done it.”

In addition, in May 2025, it was reported that Millennium Media is producing a prequel film titled John Rambo, directed by Jalmari Helander. However, Sylvester Stallone will not be involved in the project.

So if you are looking for information about a movie called Rambo 6 that is scheduled to be released in 2025, it is probably an unofficial project or a misunderstanding.
