Hollywood muscleman Sylvester Stallone said on Wednesday that he will train with enormous weights in order to look like a "gorilla" for his new film Rambo IV.
The 60-year-old actor, in Rome to present the latest movie installment of his other signature role, Rocky Balboa, said he was keen to finish off the adventures of John Rambo, whom he first played in 1982.
In Rambo IV, expected to be released in 2008, the indestructible warrior is recruited by a group of Christian human rights missionaries in Burma to protect them against pirates.
"He'll be a man who's lived for 20 years in the East Asian jungle and become like an animal. I'll be a sort of gorilla. To get like that I'm going to train with enormous weights," he said.
Stallone also revealed that he had once been asked to make a film in which his two most famous roles, Rambo and the boxer Rocky Balboa, faced off in a battle to the death.
He said he had turned the offer down because he couldn't see how it would work. "Rambo would have won: a big bang and it would all have been over".
Stallone said his advancing years were no problem when it came to keeping the muscles on which he has based much of his film career. He was even able to eat junk food at times.
"Today I eat all sorts of rubbish and tomorrow I eat fish and salad. I train only three times a week, for an hour, and I feel in better shape than 20 years ago," he said.
