Monday saw the release of <a href=http://www.newsarama.com/20649-x-men-days-of-future-past-trailer-2-sentinels-in-action-mutant-mayhem-reigns.html>another <b>X-Men: Days of Future Past</b> trailer</a>. While there are some notable absences, like just a quick running glimpses of Bishop, a character who may be important in this time travel story, there are plenty of things you should be watching out for. <p>From the obvious - like the official debut of the Sentinels (even future versions like on the left) - to the not so obvious interpersonal dynamics of Xaviers young and old, here are ten important things we noticed in the <i>new</i> <b>X-Men: Days of Future Past</b> trailer.


Despite conflicting reports of whether Storm's role in <b>Days of Future Past</b> has been reduced, she sure has gotten a lot of screen time in both trailers so far. That suggests that either she is in fact a core character in the movie, or that her scene is pivotal or important. <p>From the looks of it, Storm's fate in the movie may be pretty similar to her fate in the <i>Days of Future Past</i> comic. If that's the case, it would indeed be a major scene, allowing her to still play a big role in the film despite a lack of actual screen time.


We know that Mystique's defection to Magneto will be a major sticking point between young Erik and Charles - Xavier specifically says as much - but where do her loyalties actually lie? <p>From the looks of things, Jennifer Lawrence's young Mystique could be the ‘x-factor’ (sorry) that sparks the Sentinel revolution. She certainly seems closer to her early comic portrayal as a more politically-minded agent of subterfuge in these trailers.


In one scene, it looks as though James McAvoy's young Xavier is up and about, rather than being confined to a wheelchair as was his fate at the end of the <i>X-Men: First Class</i>. <p>We know Xavier has alternated between mobility and paralysis in the comics, and at least one character - the bouncing, blue-furred Beast - has already received an "out" for the fate that befell him in the last film. <p>Of course, the short clip of the young Xavier up and about in the long “X-Mansion” hallways turning on lights is directly followed by him in a wheelchair. It could be simply a scene inside Xavier’s mindscape - which would also explain the Xavier-meets-Xavier scene teased in the trailer.


On the other hand, it looks like Patrick Stewart is getting in on the action like never before. Several short moments in today's trailer make it look like he's going to go toe to toe with Sentinels at least once in the film. <p>We've yet to see Xavier - especially old Xavier, at the height of his power - really cut loose in an X-Men film yet. While <i>First Class</i> saw him don the yellow and blue flight suit with the rest of his team, he still wasn't exactly "hands on."


It looks like Xavier won't be the only one getting his moment to shine, either. Several key scenes in the trailer show Iceman at what could finally be considered "full power," even sliding on ice trails. <p>On top of that, we've got scenes of Colossus, Blink, and Sunfire all cutting loose. It may be a matter of FX catching up to ideas, or it may just be a willingness to go bigger, but <b>Days of Future Past</b> will likely see some of the most dazzling mutant powers yet on screen.


This trailer is really all about Xavier; how his two incarnations team up, and how his dream has evolved from his early idealism. The interaction between McAvoy and Stewart has been central to the film's promotion so far, and is even more on display here. <p>The important thing to note is that it seems as though old Xavier is counseling young Xavier, offering him guidance and solace. The print X-Men are no stranger to time paradoxes, but are we seeing the birth of a time-loop, or something less complex.


One of the things that really stood out about Matthew Vaughan's <i>X-Men: First Class</i> was the brighter, more lighthearted tone, especially as compared to Bryan Singer's first two films, and even Brett Ratner's <i>X3</i>. <p>But this trailer all but disavows those bright colors and campy moments for something much bigger, darker, and altogether more troubled. That said, there may be an interesting dichotomy at play between the scenes of the X-Men's bright past and dark future, but the costume direction alone, even in the scenes of the past, is step back towards the much grittier take on the team.


Call it an opportunity to clean house, a chance to trim down the cast, or even just a shot at showing some big, shocking events that could theoretically come undone through the magic of time travel, but it sure looks like not everyone is walking away from <b>Days of Future Past</b>. <p>Even major characters are in trouble in this trailer, and while in comics, nothing is permanent (especially when it comes to the X-Men), would the films go so far as to partially reboot? <i>X-Men: First Class</o> took some opportunities to contradict the much-maligned <i>X3</i>. Could <b>Days of Future Past</b> be looking to settle that score?


While the last trailer was all about tone and mood, this trailer takes a big leap into the action. We've got mutants. We've got Sentinels. We've got soldiers, guns, lasers, powers, a post-apocalyptic wasteland. This is widescreen, blockbuster stuff on display. <p>Keeping that in mind, it will be very interesting to see the interplay between the deeper, emotional moments hinted at here, especially between the two versions of Erik and Xavier, and the major, edge-of-your-seat action sequences <b>Days of Future Past</b> promises to deliver.


You wanted Sentinels? You got Sentinels. <i>Thousands</i> of Sentinels. This is the component of this film many fans have been waiting desperately to see. And while we only got a few brief glimpses at the small-scale battles between mutants and Sentinels, there's plenty of eye candy flying around. <p>From scenes of Xavier and Storm taking on the mutant-hunting robots, to Magneto seemingly taking control of their metal components, to scores of them pouring out of the sky, the Sentinels are absolutely central to this story, and that's on full display in this trailer.
