You'd think fighting ghosts would be a business with longevity, what with people dying every day and all. And wuddya know: the Ghostbusters are making a comeback, Variety is reporting.

Nearly a quarter century after they saved New York from the Stay Puft Marshmellow Man, actors and former Saturday Night Live alums Bill Murray and Dan Akroyd will be reunited in a third installment of the blockbuster franchise, the trade mag says. Their sidekicks, Harold Ramis and Ernie Hudson, are set to join them.

But the Hollywood Reporter says that while the original cast is aware of the film and may be involved, producers are eyeing a new cast.

A Columbia Pictures spokesman confirmed that a third installment is in development by Gene Stupnitsky and Lee Eisenberg, who won an Emmy for their writing of TV's "The Office." The studio official, however, would not comment on the cast.

If you need a fix in the interim, a new 2GB flash drive will come preloaded with the original Ghostbusters -- the first time a feature-length film has been installed on the device by a manufacturer, according to Custom PC. Alas, a company official says that it's only available in the U.K. –- and there's no word on when it might cross the pond to the U.S.

The first two Ghostbusters movies grossed $500 million worldwide. And with Zool hangin' out in our fridge and all, we have to confess: we're psyched that the Ghostbusters are coming back for more. What about you?
