Mrs. 'Arris Goes to Paris

This movie was based on the book "Mrs. 'Arris Goes to Paris" by Paul Gallico published in 1958. Paul wrote a series of four books about Mrs. 'Arris - "Mrs. 'Arris Goes to Paris", "Mrs. 'Arris Goes to New York", "Mrs. 'Arris Goes to Parliament", and "Mrs. 'Arris Goes to Moscow".

When Mrs. Harris first sees the dress in her employer's bedroom, she is told it cost four hundred and fifty guineas. Mrs. Harris later tells Violet that it is worth four hundred and fifty pounds, and when she goes to Paris, that is what she buys it for, but a guinea was worth 21 shillings, and a pound only twenty, so 450 guineas is not the same as 450 quid, and the guinea price would make it 472 pounds, 10 shillings.
