They may be up to the task of saving the world, but could the fearless foursome from Space Cowboys endure 39 days on a tropical island in the South China Sea? Well, Clint Eastwood, the film's star and director, insists that he would have no problem going the distance on CBS's reality smash Survivor.

"I could survive alright," he tells TV Guide Online. "But I wouldn't be interested in going out there and being a part of a show like that. It sounds to me like you've got to be interested in that sort of thing."

As it is, the 70-year-old film legend, who plays one of four aging astronauts sent back into orbit in Space Cowboys (opening today), admits that Survivor's concept sounds a bit flimsy. "I don't know how it works, but it seems to me that just voting people off doesn't really have anything to do with real abilities," he says. "So I'd be suspect of that."

Fellow Space cadet James Garner wouldn't have the patience for six weeks of tribal summits and immunity challenges. "I'd have killed them all in a week, and that would have been the end of that," he says. "I have no desire to see survivors. I'd just drown them all and forget it."

Tommy Lee Jones, meanwhile, has yet to take part in the Survivor craze. "I'm not familiar with that show," the actor concedes. "I've never seen it and I've only heard someone mention it. I don't have a chance to watch television very much." Similarly, co-star Donald Sutherland is a bit out of the loop when it comes to life on Pulau Tiga. "I've been out of the country," he explains. "It sounds like Lord of the Flies or something."
