Netflix has begun production of a series based on author Andrzej Sapkowski's Witcher books.
To clarify that statement a bit more, the upcoming Netflix series will be based on the original Witcher novels and is not directly related to the CD Projekt Red video game franchise aside from the similarities that the two naturally share.
That fact adds a slightly humorous twist to this announcement when you consider that Sapkowski recently spoke out against the artistic merit of the Witcher game saga by calling into question the medium's ability to properly tell such a grand story. Before that, Sapkowski also admitted that he chose not to take a percentage for the adaptation rights, which he later came to regret when the series went on to gross over a billion dollars.
