Who you gonna call?

There's a script for "Ghostbusters 3" and it's been sent to Bill Murray says Ivan Reitman, who produced and directed the first two. Presumably if Murray was interested the rest of the original cast could be enticed to reprise their roles. Hollywood definitely goes overboard with sequels and remakes, but I think I'd be up for this as long as it didn't turn into an embarrassment like "Indiana Jones and the Kingdom of the Crystal Skull".
