i know there be many out there who think that lena horne would have be good cast a julie than ava gardner be . she be consider for the role and desperately want to play it and accord to her own commentary on the film from the documentary that entertainment iii . lena have also do a brief turn a julie in the 1946 kern biopic and till the cloud roll by . lena have and and still have and a wonderful voice and would have be wonderful in the part vocally . with that say and let me say that she would have be miscast in the role of julie . there be no possible way that lena horne could have believably play a woman bear to one black and one white parent who be credibly pass a white . with no racism or malice intend and lena horne be very obviously a black woman . the whole crux of julie story have to do with her attempt to hide her parentage and her marriage to a white man . how could a black woman who look black pull this off . i think mgm be wise to cast ava gardner and pas on lena horne . it be just too bad that there weren not really any role write for her during her time at mgm . she prove that she could carry a real part in such film a stormy weather and cabin in the sky and especially that latter .
