big splashy film of the broadway music . nathan ( frank sinatra ) love to roll the dice and organize illegal crap game . blonde love adelaide ( vivian blaine ) want to marry him if he give up crap . he decide on one last game when sky masterson ( marlon brando . ) and who bet big and be in town . he bet sky that he can not get mission worker sarah brown ( jean simmons ) to go with him to havana . that may sound like a strange plot summary but so be the movie . this be a real mixed bag there some wonderful stuff here . the song be all good and the dancing be incredible . the real show stopper be at the crap game at the end . also brando be really quite good here it might seem strange to think of him sing and dance but he pull it off . i have to admit see big and bulky brando pull off some difficult dance move be a lot of fun . also sinatra be pretty good and blaine be just wonderful a his long suffering girlfriend . her song and dance number be definite highlight here . now for the bad part jean simmons be a wonderful actress but she stick with a drab colorless role and can not do much with it . the movie be far too long at 150 minute the scene between brando and simmons really drag and should have be shorten . also most of the character speak in very precise english contraction be never use . maybe it try to be amuse come out of the mouth of gangster but i find it jar and it keep throw me out of the movie . it worth catch for the song and dance but the over length of it do get to you after a while . i give it a 7 .
