Eternals will be the third MCU movie released since Spiderman: Far From Home saw Phase 3 of the comic book universe come to a close.
The Marvel Cinematic Universe is moving on in many ways, and the arrival of the first Eternals teaser trailer led to social media trending the name #CaptainRogers, thanks to a quote referencing the death of the former Captain America.
It is just another sign of how much attention Marvel Studios pay to the smallest things in even their earliest trailers for future movies.
We all know by now that Marvel likes to drop little Easter Eggs throughout their trailers and promos as much as in the actual movies and TV shows themselves.
