The trailer for 'X-Men: Dark Phoenix' has been released.

In the trailer, the death of Mystique is confirmed and Jean Grey returns home. The X-Men follow Grey, who is overcome with grief over the loss of her friend and she seeks out to destroy her former, superhuman family.

The movie stars Sophie Turner, Jennifer Lawrence, James McAvoy, Michael Fassbender, Jessica Chastain, Tye Sheridan, Nicholas Hoult, Evan Peters, Alexandra Shipp, and Kodi Smit-McPhee.

 "Well, the thought process behind that was to primarily show that this is a movie that is unlike other X-Men movies," director Simon Kinberg told Entertainment Weekly. "It’s a movie where shocking things happen, where intense, dramatic things happen. People don’t just fall off buildings and dust themselves off and walk away. There’s a reality to this movie and a consequence to this movie. Even more than that, it was to show that Jean/Dark Phoenix is genuinely a threat to everyone, including the X-Men." 

He added:

"I had a lot of emotions about it. I was obviously sad about it, as Jen’s friend, and also as a fan of Jen as an actress. But I felt it was the strongest, most dramatic thing for the movie, and sometimes you have to make those kinds of hard decisions to service the larger story. And the larger story really is Jean cracking up, losing control because she’s more powerful than anyone else in the world. To dramatize that properly, you have to show real loss, you have to show real pain and show real threat and menace. "
