, 55, plans to reactivate his second most famous movie role, that of former Green Beret John Rambo, and give him a contemporary twist, London's Sunday Times reports. The "Rocky" star, whose box-office performances have been rocky of late, is currently at work in his Miami home on the script for a fourth "Rambo" adventure with an eye to a summer 2002 release, says the Times. In the new story, Rambo parachutes into Afghanistan to battle leaders of the Taliban. A possible storyline would involve the pumped-up hero with the oiled chest capturing terror chief Osama bin Laden alive. It would not mark the first time that Stallone's creation has gone marching with guns blazing into Afghanistan. (The "Rambo" series kicked off in 1982, with "First Blood") In the last outing, the 1988 "Rambo III," the character went behind Soviet battle lines to rescue his former superior. Earlier this year, Stallone said he had mixed feelings about coming back 13 years later for one more Rambo outing. "I don't know if I'd look good in a thong anymore," he told an interviewer. "In my fantasies, I'd love to do one more, but I don't think it would be in good taste at this age." Last March, Bob Weinstein, of Miramax Films, said that he hoped to convince Stallone to do one more Rambo movie. "We'd love nothing more than for Stallone to be involved," said the studio chief. "We think it's a billion-dollar property."
