Why, pray tell, is it that "The Quiller Memorandum" with its excellent cast, crisp dialogue, mildly sardonic hero, luminous Senta Berger, and above all the magnificent John Barry score, is so unsatisfying? Surely not because it is neither as bouncy as Bond not depressing a "The Spy who Came In From The Cold". Not because of the acting, which even including George Segal, is quite fine. Not because of the writers, with Pinter doing the screenplay. Something is hopelessly wrong with the ending. One is left with a bad taste in one's mouth (if one has paid attention) for we find that Quiller is not a hero at all but an unprincipled fool. I am glad I finally got to see "Quiller"; I will not be watching it again.
