The O.J. book project — and forgive the metaphor — will seemingly never die. Publisher Judith Regan may have left the building, but the Juice’s coterie is still shopping a page turner from the disgraced football has-been. The old “fictional” aspect of the If I Did It Regan deal seems to have been scrapped; now publishers and agents are, says O.J.’s lawyer, “clamoring” for a memoir. (We don’t know if receiving three e-mails in one day, as attorney Yale Galanter says he did, necessarily constitutes “clamoring,” but prevarication-wise, it’s progress.) Galanter claims he’s got a profit-sharing deal worked out between O.J. and Ron Goldman’s family — to which Simpson owes millions on a civil judgment — but Fred Goldman, Ron’s mustached dad, doesn’t seem too hot to get on board. (Astonishing!) Still, we understand why agents and publishers are so eager to follow in Regan’s footsteps. Sure, the first deal was an unmitigated disaster, but the ruthless, delusional psychopath at the helm managed to weather the media assault and the eventual unraveling of the project without killing anyone — so it’s probably safe to enter the room now. Oh, and, also, he seems like such a nice guy to work with, doesn’t he?
