I merged Dark Phoenix with X-Men: The Last Stand and a little bit of X-Men: Apocalypse.

Months back, clickbait merchants and rumour mongers were keen to share news that there would be some kind of Deadpool connection in the ill-fated Dark Phoenix movie. While this somewhat manifested a year earlier in Deadpool 2 with the X-Men's cameo in that film, there was no surprise cameo from Wade for this.

So while binging both movies I worked out a way of integrating several choice scenes from Deadpool 2 into a cut of Dark Phoenix that gives the movie not just something that brings two well received X-Film franchises together (and yes, the fact both of these films have the same initials in their titles doesn't escape me), but also provides closure to the series that doesn't corrupt the timeline the way the original version of Dark Phoenix did, and also sets up a hypothetical fifth film in the First Class timeline to show the saga of the X-Men really ought to have continued.

Two other minor tweeks aside, I left the rest of the movie alone

Jean Grey begins to develop incredible powers that corrupt and turn her into the Dark Phoenix. Now the X-Men will have to decide if the life of a team member is worth more than all of humanity.

All deleted and extended scenes, plus an alternate ending have been masterfully reintegrated into the movie. adding 5 new scenes and 4 more minutes of footage.
