Developing as a much more faithful adaptation of the comics, Jean Grey will be on a space mission at the start of X-Men: Dark Phoenix, but everything will start to go wrong when they encounter a mysterious cosmic force.
Thankfully, this will not happen with X-Men: Dark Phoenix, as it’s been confirmed that Sophie Turner’s version of the telepathic telekinetic will be the central character in the movie.
One could argue that the greatest mistake made by X-Men: The Last Stand was not telling the story through the eyes of Jean Grey — instead opting to make Hugh Jackman’s Wolverine the protagonist.
Despite Jean’s moral heart, she becomes an incredible threat that Professor X and his team must deal with.
