[UPDATE: Be sure to check out our in-depth breakdown and analysis of the trailer!]
It had to happen. Perhaps it was just inevitable. Looking at it from the perspective of long-time fans or from a marketing standpoint, it just made sense. Hugh Jackman's Wolverine needs to be in X-Men: Apocalypse.
And he is.
It's not as spoiler now to say that the early rumors and reports (as self-contradictory as many of them were) that Wolverine would make an appearance in the followup to X-Men: Days of Future Past. It's not a spoiler because the studio, Twentieth Century Fox, really wants you to know this fact. That's why Hugh Jackman appears in the new (and final) trailer for X-Men: Apocalypse.
Some fans may not like having this particular surprise spoiled and there is an argument to be made about whether or not this is or should have been kept a surprise - but from a business perspective, it was a given. Outside of Ryan Reynolds' Deadpool, Hugh Jackman's Wolverine is Fox's only bankable star - so just like Warner Bros. included Wonder Woman in its marketing for Batman V Superman: Dawn of Justice and just like Marvel Studios made sure fans knew Spider-Man would suit up for Captain America: Civil War, so too is Fox leaning on one of its most popular characters to help sell the studio's 2016 team-up event movie.
And since the marketing has mostly been met with mixed reactions (the studio isn't very good at crafting marketing materials for their non-Deadpool Marvel movies), Fox had to do something to build hype in the wake of the buzz of Captain America: Civil War if the studio hopes to also find blockbuster success at the box office in May.
