The latest trailer for X-Men: Days Of Future Past is here, but it may result in more questions than answers for those unfamiliar with the X-Men franchise. Don't worry, we're here to help.

In the trailer, it is revealed that the future isn't so great for mutants after a push by the government to capture or destroy outlawed mutants. Since the writing is on the wall, Professor Xavier (Patrick Stewart) sends Wolverine's (Hugh Jackman) mind back in time to his past self to convince a younger Professor X (James McAvoy) to change his ways.

The young Xavier is still boiling over the events of First Class, which resulted in him being paralyzed and at odds with Magneto (Michael Fassbender/Ian McKellen). It appears while they fight it out, Mystique (Jennifer Lawrence) has gone rogue and is going to assassinate someone - which will set into motion the events of the future. Got all that? Let's try to answer a few burning questions:

Aren't Professor X and Magneto dead? The two were dead or dying in The Last Stand, but comic book heroes are rarely dead for long. Whether they attempt to explain their resurrection (they made a cameo at the end of The Wolverine and only said they were "not the only ones with great power") remains to be seen.

Isn't this wildly different than the comic series? It is. In the comic, Kitty Pryde is sent back in time into her younger self to stop the mutant holocaust. However, Ellen Page's character hasn’t been developed in previous titles and - let's be honest - Wolverine is the money-maker for Fox. There is also a connection to this storyline and the Age of Apocalypse, which is the basis of the next X-Men film - but we don't want to spoil it.

What's going on with Peter Dinklage? Dinklage plays Bolivar Trask, who uses an assassination by Mystique to wage war on mutants - using Sentinels created by the company he owns. As such, he spends quite a bit of time lobbying the government and using scare tactics for his own gain.

Did I just see Storm die? Probably. Halle Berry's role has allegedly been cut down quite a bit, and in the 1980 comic many X-Men perish while fighting the new Sentinels. It's interesting they placed the scene in the trailer; but we suppose it's possible someone saves her at the last moment. It's important to note that the whole point of the movie is to keep future events from happening, so don't fret if a favorite dies off.

X-Men: Days of Future Past will hit theaters May 23.
