Any day is a good day to chat with action hero Sylvester Stallone, particularly when the topic of conversation turns from the highly anticipated "Expendables" sequel to the always-anticipated "Rambo" sequels. 
 
 The last time we checked in with Stallone about the future of his famed Vietnam vet John Rambo, it seemed as though there might not be any more story to tell and that the hero needed "to stop running" and take a rest. 
 
 Thanks to our recent run-in with the main man at CinemaCon, it seems as if Rambo's rest has come to an end and we might see him rise again. 
 
 "There's a volcanic eruption [brewing]. The magma of Rambo is coming to the surface," Stallone said when asked about his thoughts on bringing the character back to the big screen. 
 
 So is there another story to tell? 
 
 "I know there is," he said definitively. "It's one thing where you lay down the final culmination of your life where you can articulate it, but also act on it where he realizes what his destiny really is," Stallone said, speaking for the character and how he might take a moment to reflect on his life and realize his work isn't finished. "It's not to be a farmer, it's not to be obscure; it's to go out in a blaze of glory in a heroic fashion. But is he really doing it for himself or is he doing it because that's just his id? That's who he is. 
 
 "I like the whole Mexican situation, what's going on down there," Stallone continued, hinting at the film's possible setting and building the plot around the real-life conflict in Mexico. "So I'm working on a formula for it right now."

 Sylvester Stallone says, at the age of 65, he is ready to don his jungle gear again and star in Rambo 5 . 
 
 The actor says he is working on a script that will see the former Vietnam veteran fighting his final battle. 
 
 In an interview with MTV, Stallone hinted that the veteran mercenary’s last showdown could take place in Mexico, in a battle against the drug cartels. 
 
 Stallone first played Rambo in 1982 and made three sequels – the last of which was released in 2008. He added: "It's one thing where you lay down the final culmination of your life where you can articulate it, but also act on it where he realises what his destiny really is. It's not to be a farmer, it's not to be obscure - it's to go out in a blaze of glory in a heroic fashion ... That's who he is. 
 
 Stallone, who recently finished filming Expendables 2, added: "I like the whole Mexican situation, what's going on down there. So I'm working on a formula for it right now." 
 
 What's your favourite Rambo so far? 
 
 When filming First Blood, Stallone is alleged to have violently clashed with the director, Ted Kotcheff, at one point breaking three of his ribs. And he objected so vehemently to the original ending where Rambo committed suicide, he was sued by the studio to ensure he would return to the set and film it. 'After the first screening in Las Vegas, I went out into the alley and threw up. It was all wrong. Artistically totally correct. Emotionally totally wrong.’ The ending was reshot with Rambo getting to live. 'That’s the difference. It’s not naturalism. It’s dramatic realism. The films are realistic fantasies. Bullets are easy. You can buy ’em. Emotions are not. They’re priceless.’ 
 
 Asked in 2010 whether he would he want to do another Rambo, Stallone replied: "God, no. There’s nothing left to kill!". Step forward the Mexican drug lords.
– Rambo isn't done fighting yet: The action hero will "go out in a blaze of glory" in Rambo 5, Sylvester Stallone revealed in a recent MTV interview getting picked up today. Stallone, 65, is working on a script revolving around John Rambo's final battle, and he implied that the Vietnam veteran could find himself fighting drug lords in Mexico, the Telegraph reports. (Quote that probably came out wrong: "I like the whole Mexican situation, what's going on down there.") In the planned film, Rambo—who last came to the big screen in 2008—"realizes what his destiny really is," Stallone explains. "It's not to be a farmer, it's not to be obscure—it's to go out in a blaze of glory in a heroic fashion."
