Although filmed in the US the film portrays the scenery of Albania very well. In 1971, there were few books and information about the country. One error that stood out was in the market where there was a sign showing the direction to Tirana.

Producer Frederick Brisson turned down a request from Albania's United Nations delegation to desist from using a pair of Albanian flags in the movie.
