i would not try to speculate a to what brando be attempt . at his best he turn in such oddball performance and insinuate so many thing at once and that it doesn not seem he do anything so much a play by unfailing instinct . often it seem he be call attention to some favored aspect of his character over all others and a concentration which and if follow and turn out something of a red herring and a he turn out subtler and crafty than at first appear . this be a mastery of artifice and not naturalism and a might be associate with the method . the role of sky masterson and a mankiewicz so wonderfully realize and seem tailor for him and which be to begin with odd and and odd still at the end and because whatever it be brando have do and he have manage a grace maybe all his own and but a consummate grace nonetheless again and odd and come from an actor with limited musical ability and not ever before or after associate with the musical comedy . jean simmons and also oddly cast and be not quite a impressive and but certainly above just adequate and really delightful in the havana sequence and and never less than enjoyable throughout . and yet . perhaps because actor be both so concentrate on what it be they be do and and character on what it be they intend of each other and there doesn not seem to be the lover chemistry bring up so insistently more than once . brando or sky masterson and simmons or sister sarah respectively fee off one another well enough and but i for one do not see more beyond that . in a movie this outrightly dazzle and entertain ( and most everything about it and craft wise and be just that dazzle ) and that lack would seem something tactfully and easily overlook and but so much would depend upon true chemistry . an and at least partial and transformation of the character through such chemistry and would lend something positively move to the final scene . a it be and one leave this film certainly delight and but not really move and except in a way a to negate the trueness of the union . note sister sarah marries in her missionary uniform and sky masterson in his same natty man about town dud rather than wed tux . and they have change back to those from their previous scene . funnily enough ( that be and insightfully ) and the most touching and and most serious and scene be and i think and between brando and vivian blaine and a sinatra or nathan detroit doll and adelaide and the only scene where these two be exclusively together and not least because there be just no hint of flirtation between them even though it take place in adelaide dressing room while adelaide be about to change . though one may submit there be no place for that and sky really be the type to check out adelaide in this sort of circumstance . he be even there to tell adelaide nathan will not be meet her to elope . adelaide and sky be both true in their respective way to nathan and even piteous of him and a be demonstrate through a tone in their exchange . adelaide be of course also frustrate and disappointed and but her anger be mitigate by her deep feeling for nathan and a sky be admonish her that she can not love a man and then wish him to be someone else . guy and doll be another turn at the battle of the sex and around the theme of gamble and salvation . since both the compulsive gambler and the salvation seeker be more or less unconsciously court despair and there just may be a dark secret deliberately behind brando and simmons lack of chemistry . after all and that lack may well denote an excess of narcissistic preoccupation ( echo by the sinatra or blaine pairing and though with considerably less self deception involve ) and which might explain brando and simmons odd and rather provoking and interpretation of sky masterson and sister sarah . i realize simmons may be mostly depict coldness and skepticism and but brando and though play to confront her and isn not exactly heat and eager and and be more than keep his distance he also assimilate it and keep his balance through it . his boldness consist in merely play against her the trip to cuba and a kiss and whatever it take but he be not actually set on win through seduce her so much a beat her then in her own turf . this may be shrewd and a play to zeal may be the only way to get to the missionary and and through . but it make sky transition from merely try to win a bet to actually want sarah brown a little less than persuasive . yet why do he want her . what do fall in love mean to sky . i find the only way to get around this be by indeed accept his humanity have kick in and and that he do not want to end up a mere cad toward sister sarah and so he do and a he promise her and need to deliver the sinner to her prayer meeting and make good by his marker and a he put it and a a way of win her back when it seem he have already win only to lose her . but this still denote self concern more than anything . however and it also allow for sarah brown own self concern and a sky will placate the missionary in her in order to get back the lover . neither and at least it seem and will change much by their union and except perhaps in the acceptance of the other . yet that would seem an all but fatally uneasy proposition represent acceptance of be still quite a cry away from achieve happiness in the other and let alone the transcendence they each seem to imply by chemistry . and behind all this and i suspect be mankiewicz full knowing . for all those who might say and in defense of guy and doll yet and that not much can be expect from musical by way of depth and i need only remind them cabaret and the three penny opera and carousel and a star be bear and even the sound of music and which i do not care for as much ( and one can keep add to this list without even reach forward toward post cabaret musical ) and all wrap gorgeous music and dance around dire anxiety .
