Bad luck ... I happened to purchase - on a whim - the original "arrow" paperback novel a sheer week prior to finding out that the motion-picture adaptation was being shown nearby, with tentative acting by no less than Etan Hawke and (!) Kristin Scott Thomas ...; all the more than tantalizing ...; Having read through Kennedy's incredible/unbelievable story, I was more than curious how -the heck- both script-writer and Director would/had rendered , or came-out of this lame ending tale ?! Lo and behold, it's even worse than I had expected ...: gloomy, pessimistic, unhinged -since some/most characters' interaction(s) are left out- with Ricks and Margit factual plain physical relationship wholly left out ... being compensated by an 'end-of-second World War' Parisian feel and atmosphere ... ?! Neither are these credits any justification for leaving-out some of the original script justification &/or relating's ...; The whole experience become/come-out as an WIDE AWAKE NIGHTMARE of unrealistic happenings ...; P.S.: credited appraisals by 'Mail on Sunday' and 'The Times' literary critics must have been disclaimers ...
