Cherry10 could not have known Marylin Miller in the 60's. Marylin Miller died in April, 1936. She died after complications from sinus surgery. The movie only touches on this at the beginning when she became dizzy while dancing at the rehearsal. The movie takes some artistic license in presenting only "the sunny side of life" for Marylin, with the exception of the death of her first husband, Frank Carter. She actually went on to marry three more times. The movie succeeded in bringing an entertaining musical to the screen and did serve as a showcase for Ray Bolger. June Haver was able to keep up with him and did shine in her dance numbers.
