Factual error: The movie is set in 1922, but the women's clothes are more along the line of 1928, with a strong 1960's influence. For an accurate depiction of 1922 fashion, refer to Season 4 of Downton Abbey.
Thoroughly Modern Millie (1967)
1 factual error
Directed by: George Roy Hill
Starring: Julie Andrews, James Fox, Mary Tyler Moore, Carol Channing
Revealing mistake: In the beginning when Mrs. Meers goes into the elevator, you can see that the elevator floor is a continuation of the room floor, just with a strip across it.
Muzzy Van Hossmere: Myself, I prefer to sleep in the all-together.
Trivia: During the title sequence, as Millie is buying a pack of cigarettes from a vendor, her undergarment breaks. The vendor stares at her in surprise, and she does a slight curtsy and walks away. When the film was originally released, that was followed by a quick shot of the vendor looking down and seeing Millie's broken undergarment lying on the sidewalk, but for some unknown reason, that shot has been deleted.
