Trivia: Three costumes were made for Streisand for the "Hello Dolly" number at the Harmonia Gardens. They are identical except for the length of the train. As she enters she has the dress with the full train. During the number the train "shortens" twice to enable the dance steps, particularly the backsteps, to be performed and for the last few bars she is back to the full train original dress.
Trivia: Director Gene Kelly's first choice to play Minnie Fay was not E J Peaker, but Sandy Duncan, who he had seen dance and sing on Broadway and was perfect for the part - she did a screen test but was turned down. Kelly next wanted Ann-Marget but was also turned down. Peaker went on to a short nine film career, Hello Dolly was her first, she was better known for her TV work.
