X-Men: Days of Future Past (2014) Fantastic Four: Doom Strikes (2015) X-Men: The Mutant Massacre (2016) Fantastic Four: Annihilus Annihilates (2017) X-Men: Age of Apocalypse (2018) Fantastic Four: Galactus Returns (2019) X-Men & Fantastic Four: Attack of the Skrulls (2020) Here's my idea/suggestion on how FOX should make their own cinematic universe. Since the only major properties from Marvel that 20th Century Fox has are X-Men and Fantastic Four. I think those two should be their main priority. Forget about spin-offs for smaller X-Men characters and prequels. What they should be doing right now is how to make X-Men and Fantastic Four as large as the other big movie franchises right now. With the X-Men, after Days of Future Past. They should forward to the present timeline and bring back the original cast of the X-Men series again. At least make 2 films with them and include new faces to the team like Psylocke and Forge. X5 should be an introduction to another big X-Men villain in the comics, Mr. Sinister. Then what happens to X5 leads to X6. Mr. Sinister is the main villain for X5 but at the end of the movie, there will be a big villain that Mr. Sinister is only working for a more powerful mutant, Apocalypse. Then Apocalypse will be the main villain for X6. And I don't want a trilogy where Apocalypse is the main villain, I think it could be tiresome so I think he should be the main villain for only 1 film. Then for the Fantastic Four, I want them to be big first before teaming up with the X-Men. The box-office performance of their movies should be good and the films should be as good as the X-Men films, or at least good. And like the X-Men 4 to 6, give the series a bigger scale so it would really appeal to a lot of people. Then after another successful trilogy from the original cast of the X-Men and a successful Fantastic Four trilogy. The next step should be, how can these two superhero teams appear in a bigger movie after their successful trilogy. The solution - make X-Men and Fantastic Four work together. X-Men go could to space for the first time and Fantastic Four will work with a more well-known superhero team. Its a win-win situation if done right and I believe it could be a massive hit. You have 2 superhero teams that had a successful trilogy and they are now coming together. I also think it could be the perfect time to bring the Skrulls. They invaded the earth and Fantastic Four/X-Men will stop them. Another idea for the cross-over film is have Magneto/Dr. Doom help Fantastic Four/X-Men. Anyway, its just my wishlist. But the Fantastic Four reboot has to be really good and successful first if FOX is really planning to make a cross-over film with the X-Men and the Fantastic Four.
