Great camera angle of Superman flying!! Except there's something with ... and Isabela Merced as Hawkgirl. It's also been confirmed that Milly Alcock's Supergirl will be introduced in the movie ...

There's not much of a look at Hawkgirl in the trailer, but she can be seen flying through the sky at one point. We know she'll be played by Alien: Romulus actor Isabela Merced in the new movie.
