istanbul be another one of those expatriate film that errol flynn be make in the last decade of his life try to support his family and stay out of trouble with the irs . it a remake of the fred macmurray ava gardner film singapore from a decade ago . unlike that studio product and istanbul have the advantage of that great location cinematography right at the sight of the golden horn . but errol flynn and who be age exponentially before the camera in every film and be way too old to be play these action or adventure type any longer . his scene with cornell borchers really do lack conviction . a for cornell and she play errol former sweetheart who through the trauma of be save from a fire now have amnesia . she both doesn not remember errol and be now marry to torin thatcher . but errol get some nasty people lead by martin benson and werner klemperer who be after some diamond which have come into his possession . get to deal with them too . best reason to see istanbul be to hear nat king cole sing and play the piano . most people today do not realize that cole be an accomplished jazz pianist and they only think of him a a singer . actually he be a pianist first and the singing be an afterthought . istanbul be a routine action or adventure film for those who be fan of that type of movie .
