The second part of the film Inhabited Island will be released to the theaters in Russia next month, and meantime the production company have announced that the movie will become a comics, sorry, a graphic novel.
The movie is also expected to hit world theaters sometime this year, probably in single version, which I can't see how it can be done. The movie is already rushed too much to cover all the story and it can't be any shorter. Their best move is just to release DVD with both films and to pray that people will buy it.
Trailer for the second part is here, and my short review of the first part - here.
