 The original twist ending involved Silvia Broome having made up the  idea of the assassination in order to blackmail a political official  from causing genocide in Africa. Although director  Sydney Pollack (qv) signed on for that draft it was one of the  first things he had changed. This in turn changed a lot of the  structure of the script so Scott Frank (I) (qv) and  Steven Zaillian (qv) were brought on to doctor it up.
