Part 3/13:
One of the recurring themes in the trailer—and the broader promotional campaign—is that Marvel is trying to explain where the Eternals were during significant events like Infinity War. This retcon is an attempt to justify why the Eternals didn't help fight Thanos, with some responses humorously implying they were simply not cast yet. Such excuses have been met with eye rolls and criticisms, as they feel like a desperate attempt to shoehorn these characters into the larger Marvel Cinematic Universe (MCU).
