just saw this movie version of frank loesser guy and doll for the third time with my mother who have never see this before . she be pleasantly surprise by the singing voice of jean simmons and marlon brando . and she think the havana sequence where simmons and brando dance up a storm be excellent . those be pretty impressive to me too and be usually the highlight of the film . direct by joseph l. mankiewicz and this movie which originate a a story by damon runyon take a while with the slow pacing of the non musical scene at first but pull you in after a while . the other story with frank sinatra and vivian blaine wasn not a compelling to me but still have their charm especially during the sue me number . also love stubby kaye sit down and youre rock the boat number and the performance of sheldon leonard and b. s. pully . with a theatrical look throughout and guy and doll isn not a great film musical but certainly a very good one .
