From the beginning of "Stargate Atlantis", the producers were looking for actors to play non-Americans to present the cooperation between different nations and other groups of people in an alien environment. In fact, although in the series it is possible to see soldiers and technicians wearing in their uniforms flags that identify them as Russians, Japanese, South Africans, Belgians, Germans, Britons, Spaniards, etc, all main and secondary characters of earthly origin, except Zelenka, are from the Anglosphere: Americans, a Canadian and a Scotsman.
