Even at an interpretive level these don't make sense, unless the artists had never seen the movies at all. If I can't identify an element from the movie in the poster, it stops being a movie poster and simply become an art piece. I can't go draw an image of a turtle and call it a jaws poster.
You're not looking close enough....
Space Cowboy is Han Solo.
Rock Monster is Jabba the Hut with the Death Star over him, plus the warp speed light streaks.
Alien Sex Party is Mos Eisley.
The only one that has little to do with the movie is Cat Vader.
Again, this is interpretative art at it's finest, imo. Artists who lived under communist pressures creating their own unique visions of the first American film to be released in Russia. Interpretations that you simply will never see from a western artist.
I'm honestly shocked that not only do you guys think these are bad, but you can't even form a connection between the posters and the movies. I thought HDN was comprised of mostly affluent, educated people that didn't need things spelled out for them, but especially the damn Space Cowboy being Han Solo.
Can late 80's, early 90's Russians really have a better imagination the people on this message board?
