"It’s so rewarding after so many years in the Biz to be truly excited about being in an extraordinary scene. @rambomovie #rambo5," Stallone, 55 wrote alongside a snap which shows him dressed in Western attire.
According to the official IMDB page for the film, "Rambo goes up against a Mexican cartel in what's reported to be his last adventure."
While the whole project has been quite top secret, The Hollywood Reporter has given fans more insight, by suggesting "Rambo 5: Last Blood sees Vietnam vet John Rambo take on the Mexican drug cartels after the daughter of one of his friends is kidnapped."
The publication also confirmed that Paz Vega will play the role of Carmen Delgado, "a reporter who covers the Mexican drug trade and teams up with Rambo after her younger half-sister is kidnapped."
