 When the taxi pulls up with cousin Miriam inside and stops at the  foot of the steps, if you look closely before Miriam gets out you  can just for a split moment see it is fact Joan Crawford (I) (qv)  in the back and not Olivia de Havilland (qv). You cant see  Crawfords face but you can tell its her by the black dress and  dark sunglasses that she is wearing. When de Haviland as Miriam is  seen in the taxi before she arrives she is wearing a white hat and  her clothing is light colored.
