A SPIRITED FINALE

Ghost Whisperer executive producer John Gray promises "a big surprise ending" to the just-renewed CBS series' first season, setting the stage for a sophomore year with "darker elements." "We're not going to mess with our formula too much," he tells Sci Fi Wire. "At the same time, we don't want it to get stale." Citing as examples the mysterious entities he calls Laughing Man and Wide Brim Hat Man, Gray says, "We're going to be giving some explanation for their presence." What, they're not just ogling Jennifer Love Hewitt like the rest of us?
