Unlike the previous three, which released every three years in the 1980s (“First Blood” in 1982, “Rambo: First Blood Part II” in 1985 and “Rambo III” in 1988), “Rambo” exactly two decades later featured some commonalties and also broke some new ground.

Sylvester Stallone – who’s now 61 years old, and though he shows it, still looks the buff part – of course starred in all of them as John Rambo. In addition to starring in the films in 1982, 1985 and 1988, Stallone was also a scribe. The films were all directed by other talents (Ted Kotcheff, George Cosmatos, Peter MacDonald, respectively).
