At any rate, I found this interesting:
The film is to be based on the novel Cloud Atlas, and I decided to look around to find more about its portrayal of "dystopian Seoul in 2144." As it turns out, Gypsy Scholar read the book last year and blogged several times (1, 2, 3, 4, 5) about that book (and others by writer David Mitchell, who taught English in Japan for years) and its connections to Korea.
Bae will appear in the sixth episode playing the role of cloned human Sonmi-450 in a dystopian Seoul in 2144.
As he notes here, "The story, which I've only begun reading, seems to depict a future Korea in which the North and the South have unified into state capitalist version of a corporatist Juche society."
Sounds like fun. I'll be curious to see how it turns out in the finished film, especially considering how abysmal Korean-made science fiction films set in the future have been (these two come to mind, and on that note this post by Gord Sellar is worth a read).
