David Harbour is heading into the “John Rambo” war zone. The actor has joined Lionsgate’s prequel opposite Noah Centineo, with Harbour set to play Major Trautman, the commanding officer and mentor figure at the center of Rambo lore.
That makes Harbour a meaningful late addition to a project that is already well underway. The film began production in Bangkok in January, with Jalmari Helander, the filmmaker behind “Sisu,” directing from a script by Rory Haines and Sohrab Noshirvani.
Set before the events of “First Blood,” the film goes back to Rambo’s Vietnam-era beginnings, with Centineo playing a younger version of the character long associated with Sylvester Stallone. The cast already included Yao, Jason Tobin, Quincy Isaiah, Jefferson White, and Tayme Thapthimthong, and Stallone joined the production as an executive producer last month.
Harbour’s part is not some throwaway supporting slot, either. Trautman is one of the defining figures in the series mythology, the officer who understood what Rambo was, what the military made him into, and how little space there was for someone like him once the war was over. On screen, the role was originally played by Richard Crenna, making this one of the franchise’s more loaded handoffs in its long afterlife.
There’s still no release date, but the shape of “John Rambo” is coming into focus fast. With filming already underway, Stallone now involved behind the scenes, and Harbour stepping into one of the saga’s most recognizable roles, Lionsgate’s prequel is clearly being positioned as more than a brand-extension placeholder. It’s an origin-story reset, and now it has one more piece in place.
