“Over the Rainbow” was nearly cut from the film; MGM felt that it made the Kansas sequence too long, as well as being too far over the heads of the children for whom it was intended. The studio also thought that it was degrading for Judy Garland to sing in a barnyard. A reprise of the song was cut: Dorothy sang it to remember Kansas while imprisoned in the Witch’s castle. Judy Garland began to cry, along with the crew, because the song was so sad.
Judy Garland had two characters say the same thing to her: “Why didn’t you tell me I was in love with you?”. The first was Gene Kelly in For Me and My Gal (1942) and second was Fred Astaire in Easter Parade (1948)
