So far the latest installment of the Rambo franchise has undergone many name changes, and has been known as the following
John Rambo - mirroring the final installment of the Rocky Franchise, Rocky Balboa, Stallone decided upon using the full name of the action hero
Rambo IV: In the Serpent's Eye
Rambo IV: Pearl of the Cobra
Rambo: To Hell and Back - On October 12th, Lionsgate announced that the film title was being changed to Rambo: To Hell and Back. After some negative feedback from the online community, Stallone spoke with AICN's Harry Knowles and is quoted to have said:
"Lionsgate jumped the gun on this. I just was thinking that the title John Rambo was derivative of Rocky Balboa and might give people the idea that this is the last Rambo film, and I don't necessarily feel that it will be. He's not an athlete, there's no reason he can't continue onto another adventure. Like John Wayne with The Searchers."
