 For box office reasons, Stanley Kubrick (qv) intended to impose a  happy ending. After several draft scripts he changed his mind and  restored the novels original ending. Producer  James B. Harris (qv) then had to inform studio executive  Max E. Youngstein (qv) and risk rejection of the change. Harris  managed by simply having the entire final script delivered without a  memo of the changes, on the assumption that nobody in the studio  would actually read it.
