Some of the distinctive pleated gowns worn in the Venice scenes are designed to look like gowns produced by the Italian designer Fortuny. Fortuny pleated gowns were popular among wealthy European women in the early 1910s for their simplicity, form-fitting design and Greco-Roman influences. The gowns in this film, however, were created by contemporary husband and wife team Charles and Patricia Lester, who create modern gowns with a similar pleat.
The tile pattern on the Underground stations the train passes through at the beginning of the film are identical in pattern and color for each station. Each station on the Piccadilly line had its own tile pattern and color scheme so that the illiterate could still recognize their station without needing to read the station name.
