Última noche en el Soho

Final performance of Diana Rigg, who passed away on September 10, 2020. The film is dedicated to her memory. Her only child, actress Rachael Stirling, receives a "Special Thanks" in the end credits.

Eloise asks the librarian for information on missing persons for the entire 1960's, but she had an obvious reference to narrow her search - Thunderball (1965) was released in the UK on December 29, 1965 meaning this was early 1966 at the earliest.

Before the film begins, it opens with a simple dedication: "For Diana". This is likely a dedication for the film's star, Diana Rigg, who died after shooting finished, but before the release of the film.
