A new trailer of the upcoming movie "X-Men: Days of Future Past" has been released. The trailer gives viewers a better look at the Sentinels and their fighting capabilities. There are many questions in the minds of fans though that only the movie can answer.

The Sentinels are mutant-hunting robots created by a scientist called Bolivar Trask. According to the trailer, the robots eventually start to target normal people as well. Viewers get to see the tall, purple robots in action in the new trailer.

The main focus of the movie is to stop the war before it begins. The mutants come together in order to save themselves from becoming extinct. Wolverine is chosen to be sent back in time to ensure that the war does not happen.

Viewers will see actors from the "X-Men: First Class" movie joined by the actors from the previous "X-Men" movies. The young Charles Xavier is played by James McAvoy and the older Charles Xavier is played by Patrick Stewart. The young Magneto is played by Michael Fassbender and the older Magneto is played by Ian McKellen. The role of Bolivar Trask is played by Peter Dinklage.

There were some eyebrows raised when fans saw the young Charles Xavier walking in the "X-Men: Days of Future Past" trailer. The character was supposed to be paralysed from the waist down. Viewers can see him in a wheel chair later in the trailer, leaving fans wondering if the movie will show new events of Charles becoming paralysed all over again.

One theory in the minds of fans is that Wolverine could have travelled in the past before the events of the movie "X-Men: First Class" took place. This would give the movie ample room to sidestep having to pick the storyline from the previous movies.

With so many characters and the concept of time travel involved, some fans are concerned that the storyline could get very confusing. But fans who are going to the theatres to only enjoy the action sequences may not be disappointed.

Another concern some fans have concerns Wolverine. Since he is going back in time in "X-Men: Days of Future Past," he will not have the metallic claws, which are indestructible, but the bone claws that he had before.

Will "X-Men: Days of Future Past" meet fans' expectations? Or will it be a disappointment? So far, the good reviews for the movie outweigh the negative reactions. It remains to be seen if this will translate into actual revenue for the movie.
