Justice League [trailer #1]

The movie is set for a November 2017 release.

From the video description:

Fueled by his restored faith in humanity and inspired by Superman’s selfless act, Bruce Wayne enlists the help of his newfound ally, Diana Prince, to face an even greater enemy. Together, Batman and Wonder Woman work quickly to find and recruit a team of metahumans to stand against this newly awakened threat. But despite the formation of this unprecedented league of heroes—Batman, Wonder Woman, Aquaman, Cyborg and The Flash—it may already be too late to save the planet from an assault of catastrophic proportions.

Supergirl makes a strong impression with the first trailer

Supergirl knows how to make a first impression, especially if this first trailer for the upcoming CBS television show is to be considered. From the video description:

It’s not a bird. It’s not a plane. It’s not a man. It’s Supergirl. In the new drama from the world of DC Comics, Superman’s cousin, Kara Zor-El, embraces her superhuman abilities and becomes the hero she was always meant to be. This Fall on CBS.
