The original John Rambo movie, titled First Blood, sees Rambo, dealing with PTSD following the Vietnam War and inadvertently crossing a small town sheriff, which leads to a standoff between the Green Beret and the local police. The new movie will tell the story, or at least part of the story, of Rambo’s time in Vietnam.

A new Rambo movie is coming. Noah Centineo will portray a younger John Rambo. The film explores Rambo's Vietnam War days. Sylvester Stallone is not involved in this project. Filming starts in early 2026 in Thailand.

The upcoming Rambo prequel has reportedly found a new actor to take on Sylvester Stallone’s famous character. Sources told Deadline that 29-year-old Noah Centineo of To All The Boys I’ve Loved Before fame is attached to star as Rambo in the new film showcasing the character’s origin.
