Alien Worlds (2020 TV series)

Narrated by Sophie Okonedo, Alien Worlds is a British miniseries that mixes science fact with science fiction. Over four episodes, it uses computer-generated imagery to imagine what extraterrestrial life could look like, basing those designs on the biological rules found on Earth and applying them to fictional exoplanets. The show debuted on Netflix on 2 December 2020.

The series became one of Netflix’s ten most-watched shows in the UK during its first weekend. In a review for Forbes, Sheena Scott described it as “entertaining and very informative science fiction,” noting that the most compelling parts were the non-fiction segments about Earth, which highlight “the breadth of knowledge scientists have accumulated about our planet.” Similarly, Emma Stefansky of Thrillist found the alien creatures enjoyable but concluded that “it's the Earth-bound science that ends up being the most interesting part.”
