Ben Affleck is still worried that all fame is fleeting.

"I just so hate the idea of achieving something and losing it," he said in the August issue of Premiere magazine. "That's the definition of a has-been."Affleck, starring in "Armageddon," shot to the top when he shared an Oscar for the "Good Will Hunting" screenplay.

"I also know that this success I'm having is nothing permanent," he said. "I have this huge fear that I'll end up 55 and broke and unable to support my wife and kids."
