After an eight-year long wait, (most of) director Bryan Singer's original X-Men film roster – last seen in 2006?s X-Men: The Last Stand returns for another super-powered mutant adventure in just a matter of weeks. X-Men: Days of Future Past brings back the heroes and villains played by Hugh Jackman, Patrick Stewart, Shawn Ashmore, Ian McKellen and Halle Berry (& more!) and sees them share screen time with the core cast of 2011's prequel X-Men: First Class.

Days of Future Past, the most expensive comic book film ever made, is the first Marvel movie to introduce time-travel, a common plot device featured in the comics, and thanks to its introduction, fans get to see the X-Men franchise veterans listed above joined by First Class stars Michael Fassbender, James McAvoy, Nicholas Hoult, Jennifer Lawrence and Lucas Till.

Like previous films in the series, X-Men: Days of Future Past deals with anti-mutant hysteria but takes it to the extreme. Mutant-hunting machines called Sentinels were created in the '70s (Nixon era) thanks to a man named Bolivar Trask (Peter Dinklage), and over the years future iterations of the machines evolved, ultimately lost control and nearly destroyed the planet. Now, the remaining mutants left alive must band together for one last mission to send Wolverine (Jackman) to the past and prevent this post-apocalyptic future from ever becoming a reality.

The first Days of Future Past teaser introduced the returning characters and the core story element of using time travel to save the world, and the second X-Men: DOFP trailer focused on the action, showcasing the new and returning mutants using their super powers and battling the Sentinels. The Final trailer is now here for Fox's 2014 superhero tentpole. Check it out and see how it compares to what we've seen from The Amazing Spider-Man 2, which releases just a few weeks earlier.

Wolverine, the star of the franchise and of this movie in particular (we even get two versions of him!), gets all the screen time as the final trailer focuses strictly on his mission to the past and efforts to recruit and unit the most important mutants capable of helping out in the '70s. We even get to see new characters like Quicksilver and Bishop in action, with their powers on display.

Fans will notice a few inconsistencies that the movie will attempt to explain, from Beast no longer being blue and furry, young Charles Xavier walking, old Wolverine having adamantium claws, etc. We don't know why these things have all been altered, but the movie will offer explanations for all of them (we hope) according to Singer.

Still, the trailer is the best one yet for the film, offering plenty of action, spectacle, mutant powers, giant robots, and of course, a little bit of character humor. If anything, seeing Hugh Jackman still owning the role of the iconic Wolverine is a strong selling point for longtime fans, even if he’s supported by one of the most impressive film casts ever assembled in summer blockbuster. Excited?
