From The Guardian:
Acquiring rights to adapt One Hundred Years of Solitude has been a hard-fought contest. García said that his father was sceptical of the sprawling magical realist novel’s capacity to fit within a traditional film structure, and wanted the story to be told in Spanish.
“For decades our father was reluctant to sell the film rights to One Hundred Years of Solitude because he believed that it could not be made under the time constraints of a feature film, or that producing it in a language other than Spanish would not do it justice,” García said. “But in the current golden age of series, with the level of talented writing and directing, the cinematic quality of content, and the acceptance by worldwide audiences of programs in foreign languages, the time could not be better.”
Call me a cynic, but I don't think Márquez would approve this if he were still alive. Plus, not entirely convinced that magical realism will translate effectively to a visual medium.
But, at least it will be in Spanish, and a series is likely to do the book more justice than a feature film.
