is a very private guy. If he were ill (Boy, I really hope that's not the case), I am not sure he wouldn't be very hush-hush about it. That would break my heart, but I am seriously wondering if an unofficial reason he's not doing Ghostbusters is because he's just unable to do the work. If that's the case, I hope he'll be honest enough with his fans to say so. Bill who? If this movie is dependent on having Bill Murry back then don't make it. It has been proven over and over again a good script with good acting and editing means more then who's in it. Get 3 new actors to play the major roles and the older ones in less important ones. Nobody wants to see 3 or 4 old timers running around in funny suits trying to do things they can't. Would anybody enjoy seeing 3 stooges movies with 70 year old men playing those parts....NO....slapstick is for younger men. As Jerry Lewis aged his comedy became less and less funny. Not because we saw it before but because men of a certain age are not funny doing certain things. I still laugh at Henny Youngman videos because he was an older man doing comedy as an older man, it would not have been funny with someone younger. Conversely having older men do that kind of semi slapstick humor is to me humorless. What works for a thirty something does not for a sixty something
