Julia Roberts, Will Smith, Robin Williams, Michael Keaton, and Jennifer Aniston are seeing ghosts

Casper, call your agent. Thanks to the success of the Nic Cage-Meg Ryan weeper “City of Angels,” tales of the afterlife have become the topic du jour in Hollywood, according to Entertainment Weekly magazine. Among the metaphysical movies ready to haunt the multiplex: “What Dreams May Come,” which will take Robin Williams through heaven and hell in search of his deceased wife; “Jack Frost,” starring Michael Keaton as a reincarnated snowman; and “Love Jenny,” likely to feature Will Smith as a widower whose wife comes back in the body of Jada Pinkett Smith.

In addition, “Something Wicked,” about a ruthless female executive who gets a second chance at life, has Jennifer Aniston attached to star. And Julia Roberts is seriously considering “Manhattan Ghost Story,” a supernatural romance. What’s with all the soul mating? “Dreams” director Vincent Ward calls it “one of those end-of-the-century things. There’s a hunger out there for a fresh view of looking at the afterlife.” But “Ghost Story” screenwriter Ronald Bass thinks it’s just a new look at an old-fashioned sentiment. “Audiences are interested in a world that says love is stronger than death,” he explains. “That stuff is irresistible.” Not to mention Michael Keaton as a snowman.
