The film was shot in South Africa. Since the country was ruled by strict apartheid (enforced racial separation) laws, stars Sidney Poitier and Canada Lee and producer/director Zoltan Korda cooked up a scheme where they told the South African immigration authorities that Poitier and Lee were not actors but were Korda's indentured servants; otherwise, the two black actors and the white director would not have been allowed to associate with each other while they were in the country.
