F. Scott Fitzgerald once declared that there were no second acts in American lives. One wonders what he would have made of one former Sweathog.

In more than 25 years, John Travolta has gone from disco cool to seriously uncool, from hit-man chic to sci-fi cheese. He's had more booms and busts than a week on the Nasdaq.

"The Fitzgerald line is so negated by our time," says film producer Joel Silver, whose credits include the Lethal Weapon, Predator, The Matrix and Die Hard series. "We're looking at people with fifth and sixth acts. John is one of those."

And that's fine by John.
