Walt Disney came to oversee the production of the film in the UK from June to September 1952. The team spent several months researching period details to make the film more realistic. Working in pre-production had helped reduce the need for natural settings in favor of studio sets designed by Peter Ellenshaw. Ellenshaw painted sets for 62 different scenes in total. According to Leonard Maltin, Ellenshaw's work was such that it is sometimes impossible to tell where the painting ends and reality begins.
