The Rambo franchise often sees John journey to whatever conflict is occurring in a given era (such as Afghanistan in the 1980s, or the genocide in Southeast Asia), so his move to Mexico seems in-line with the franchise’s willingness to take on conflicts that grab headlines.
The franchise centers on Stallone’s John Rambo, a scarred Vietnam veteran who never fully recovered from the trauma experienced during his time in the war.
However, despite the similar iconography to the Rocky franchise, Rambo is very much its own beast.
Sylvester Stallone had previously stated that he was done with the Rambo franchise, but now it seems that we can look forward to at least one more war with the classic soldier.
