X-Men (2000) Is Key to Understanding Avengers: Doomsday

Marvel is making a new Avengers movie called Doomsday, and it will include characters from the X-Men movies.

To prepare, you only need to watch the first X-Men movie from 2000.

This movie introduced the X-Men characters that will be in Doomsday, like Professor X and Magneto.

Other X-Men movies, like X2 and The Last Stand, don't matter as much because the timeline was changed.

The new movie will also be a tribute to these characters before the MCU restarts the X-Men for the next saga.
