Of course, the title didn’t last, as that concept was also rejected, leading to Rambo V landing the extremely fitting final title of Rambo V: Last Blood.
That was changed not too long after the film was greenlit under an earlier concept, which changed the title to Rambo V: The Savage Hunt.
Initially, the fourth Rambo sequel was just known as Rambo V, stylized with a Roman numeral, much like Rambo III.
That title lasted for a little while, up until that rather outlandish story was replaced with a couple of concepts, one of which was entitled Rambo: Last Stand.
