Sorry, Netflix. Before the games, but after the books written by Polish author Andrzej Sapkowski, The Witcher was adapted into a movie, and a TV series. Netflix is now developing the franchise into a new TV show starring Henry Cavill as monster-hunting hero Geralt.
The original film was known as Wiedźmin in Poland, which translates into The Witcher in English, although the film was renamed The Hexer internationally.
As the story goes, the film was released in 2001 and was panned by critics. The biggest problem being the movie wasn’t actually a movie, it was a 13 episode TV series that had been squished into a two-hour feature film, which in turn made it into a nonsensical mishmash.
