According to Variety, it looks like more George R.R. Martin work is going to hit the silver screen. According to the report, In the Lost Lands will go into production in the fourth quarter of this year and may potentially star Milla Jovovich, who is said to be in talks. The film’s story appears to be based on three of Martin’s short stories: the eponymous “In the Lost Lands”, featuring a sorceress called Gray Alys (the role Jovovich will prospectively play); “The Lonely Songs of Laren Dorr” (available online at Fantasy Magazine); and a personal favorite of mine, “Bitterblooms”, one of a number of GRRM’s stories inspired by songs (in this case, Leonard Cohen’s “Suzanne”).
All three share certain themes—there’s a deep sense of melancholy in all three, and love and betrayal runs through them all—but are otherwise unconnected, so it does raise the question as to whether the film will rework them as being part of a single narrative (which seems to be what’s implied), or whether it will instead be more of an anthology film with some sort of bridging material connecting them together. Some details can be found at Constantine Werner’s page for Rusalka Films, including some character designs and “concept designs” (actually more like design inspirations).
