Playing Against Type: Whilst this is far from the first time Marvel have hiredanoff-beatindiedirector for one of their massive blockbusters, Chloe Zhao is an especially notable case as all of her previous films (Songs My Brother Taught Me, The Rider, and Nomadland) were all quiet, intimate, naturalistic tone-poems starring or prominently featuring non-actors which is a far cry from the millennia spanning, all-star ensemble cast, epic superhero film that is Eternals.
Recast as a Regular: Gemma Chan, who plays Sersi, had previously played the one-off villain Minn-Erva in Captain Marvel. According to Kevin Feige, this was done because he deeply regretted that her talents were wasted in Captain Marvel, and wanted to work with Chan on a film once again.
Release Date Change: Much like many other cases, the COVID-19 Pandemic caused the film to delay its release multiple times. Initially slated for November 6, 2020, the pandemic shifted Eternals's release date twice: first to February 12, 2021, and then to November 5 of that same year. Notably, the second shift took it from being the second film in the MCU's fourth phase (after Black Widow) to being the third (behind Shang-Chi and the Legend of the Ten Rings).
With Chloe Zhao winning Best Director at the 93rd Academy Awards for Nomadland, she became the first Best Director winner to helm an MCU movie. She is also only the second nominee for said award to direct an MCU feature, following Kenneth Branagh (director of Thor, nominated for Henry V). Notably, she won the award during post-production on Eternals (with Nomadland having been filmed during its pre-production). Also, while Taika Waititi (Thor: Ragnarok) won an Oscar previously for Jojo Rabbit, the award was for screenplay rather than directing.
