I never really thought of how Western movies were marketed to Russia during the cold war. The posters would have to be devoid of any American influence or imagery. And that is completely obvious with the Soviet Era Star Wars Posters.
Nothing about these posters are even reminiscent of the movies we know. No wookies, or droids, or Jedis, just some weird alien like creatures, or a picture of a cowboy firing his gun in space. Check out the gallery for all the Soviet Era Star Wars Posters you could ever want.
