Look up at the sky of Rivia. It's a bird, it's a plane… it's Liam Hemsworth replacing Henry Cavill as the star of Netflix's The Witcher series.

In a surprise move, the streaming service has announced a season four renewal of its highly rated and popular medieval fantasy adaptation of popular Polish books of the same name, but with one major change – leading man Henry Cavill will be stepping down as series protagonist Geralt of Rivia, and be replaced by Australian actor Liam Hemsworth.
