Thoroughly Modern Millie

Final theatrical movie of Beatrice Lillie (Mrs. Meers). She was showing early signs of Alzheimer's disease, and had trouble memorizing her lines. During filming, Dame Julie Andrews stood off-camera and repeated Lillie's lines to her, so Lillie could complete her scenes.

Mary Tyler Moore said that she always thinks of the tap dancing scene in this film whenever she sees an elevator.

According to Mary Tyler Moore's autobiography "After All", Lew Wasserman had brought her to Universal Pictures after her unexpected success as a comic actress on The Dick Van Dyke Show (1961) with the hopes of making her "the next Doris Day" in light movie comedies. Moore contends that this film was intended as a light comedy rather than a musical, but that its focus shifted with the signing of Julie Andrews flush with the success of The Sound of Music (1965) whose character became the film's focal role with Moore's role becoming secondary. Moore's assertion is at variance with 1966 press reports indicating Andrews being attached to ''Thoroughly Modern Millie'' prior to Moore: also director George Roy Hill would state that he was given the film's script by Andrews (whom he'd directed in Hawaii (1966)). Ostensibly, Andrews had been given the script because she'd starred in the Broadway "Roaring Twenties" musical ''The Boyfriend''. Hill would also state that Moore reluctantly accepted her ''Thoroughly Modern Millie'' role, feeling she was being miscast.

In his autobiography ''The Stage Struck Me'', Neville Phillips noted the similarity between the plot of ''Thoroughly Modern Millie'' and ''Chrysanthemum'' a short-lived 1956 West End musical whose book Phillips co-wrote. Regarding his lack of legal response, Phillips opined: "What chance would an almost penniless British writer have against the might of 20th Century-Fox" - mis-identifying the studio which produced the film - "who I am sure would be able to persuade a jury that the similarities were purely coincidental. [But] personally I don't believe they were."

Theatrical movie debut of Pat Morita (Oriental #2).
