Alien: Earth release schedule – When is episode 4 out?
Sydney Chandler faces the planet's biggest threat in the new Noah Hawley series.
Warning: Minor spoilers ahead for Alien: Earth episodes 1 and 2.
Alien: Earth has emerged as one of the buzziest shows of the year to date, wowing viewers with its high production value, atmospheric sequences and weighty sci-fi concepts.
So far, the first episode of the series has attracted more than 9 million views across Disney+ and Hulu (according to Variety), with that number expected to grow as the hype continues to build.
The series stars Sugar's Sydney Chandler in the lead role of Wendy – a human child's consciousness in a synthetic adult body – who finds herself on a collision course with the franchise's iconic monsters.
Fargo writer Noah Hawley has opted to largely ignore major canon changes from Prometheus, in favour of having free rein to imagine his own dystopian vision of the future.
