3. Dark Phoenix

One of the most iconic stories in X-Men history is coming to the big screen. Dark Phoenix will take place after the events of X-Men: Apocalypse, and bring back stars James McAvoy, Michael Fassbender, Jennifer Lawrence, and "Game of Thrones" star Sophie Turner as Jean Grey/Phoenix. On top of that, another IMDb fan-favorite will be joining the cast — Jessica Chastain, who plays the mysterious character "Smith." Plus, we've been promised X-Men in space ... so it's no wonder Dark Phoenix comes in at No. 3 on this list.
