News bouncing around Hollywood is that Director Ivan Reitman is trying to get his planned "Ghostbusters" sequel green lit.  "All of the actors but one have read [the script] and loved it," Reitman tells CNN of "Ghostbusters III." "We're waiting for one of them to read it and see where we are.”  The holdout?  “That would be the famous Bill Murray — Mr. Venkman," Reitman says of the quirky funnyman, who starred alongside Dan Aykroyd and Harold Ramis in "Ghostbusters" (1984) and "Ghostbusters II" (1989).  Reitman, 64, adds that he feels the latest installment is better than the previous two movies. "I'm really jazzed about it," he tells CNN.  And if Murray doesn't like it? “We have a very complicated deal," says Reitman. "Let's just put it that way."
