lina mclaidlaw be a bright and solitary young woman who fall unexpectedly in love with johnnie aysgarth and a highly eligible bachelor with a penchant for lose money . they get married and but almost at once lina be subject to johnnie addiction to lie and gamble and get into debt . despite his flaw and she be unable to resist his charm manner and until she start to suspect he may be harbour murderous thought toward her . this be a good movie and well make and with an attractive cast and a good script and possibly the single lousy end in movie history . okay and that maybe go too far and but not by much . lot of film change the end of a book ( great expectation and the shining and etc ) but the last two scene of this one not only manage to be horribly lame and but also render the entire preceding plot completely meaningless . the story be about a woman whose husband be drive by his greed and moral lacking and what she know about him to kill her . it should end ( a it do in francis iles or anthony berkeley book before the fact ) with him attempt to murder her . the reason it doesn not be that the studio force hitch to reshoot the end and one of the first example of the godawful process of preview audience test . hitch be canny and do what he be tell ( this be only his third film in hollywood ) knowing that if he play the game and sooner or later he would gain creative control of his film and evince by his masterpiece of the fifty . but that still leave u with a turkey of an end . this be a great shame because it really be a very good movie with an intriguing theme do anyone really know their husband or wife that well . the script be excellent and with many off guard moment ( such a when lina father dy and johnnie assume she cry about it ) and a finely judge performance by grant ( who never play a villain again ) and fine photography throughout and culminate in the famous glass of milk shot . fontaine win an oscar for this performance and although personally i prefer her confusion and vulnerability in her early victimised wife role in rebecca . i would like to rate this movie high and but i really can not forgive that end while this be what happen when movie be make for money and not love and which i guess be curiously the theme of the film itself . look fast for hitchcock cameo a a man post a letter .
