You’ve very likely seen this, but the upcoming Justice League movie (The DCCU’s answer to Marvel’s Avengers) got a rather long extended trailer. As uneven as the DC comic book movies have been, this one does look like it may be good. Aside from featuring Ben Affleck as The Batman and Gal Gadot as Wonder Woman, two things about the DC movies that have been generally positive, it also features Jason Momoa as Aquaman, Ray Fisher as Cyborg and Ezra Miller as The Flash.
Check out the trailer.
