In the new trailer, as pointed out by ComicBook, when Superman is hit over the head with a can thrown by a bystander, he doesn't really react, with his eyes still facing forward. But in the original Superman trailer, when the hero was hit with the flying can, his right eye twitched in reaction. See the side-by-side comparison below.

Superman, the highly anticipated reboot of the classic DC superhero from writer/director James Gunn and starring David Corenswet. Watch it now!

This time, it’s David Corenswet in the tights, with Rachel Brosnahan as Lois Lane – and as this new trailer shows, Superman has all kinds of fights to face. There’s plenty here you won’t have seen in a Superman movie before.
