According to Comic Book Movie on Saturday, a new feature trailer for "X-Men: Days of Future Past" that focuses on Wolverine has been released. An added bonus shows his special abilities such as regeneration, super human senses, and adamantium retractable claws. Some may have already seen the full length Bryan Singer trailer where upon being shot at, one could easily see those bullet holes heal up.
The film takes an adaptation of the Marvel comic book story arc by the same name where it is Kitty Pryde, not Logan that makes a jump into the past to save the world from the Sentinels which were once programmed by Bolivar Trask , played by Peter Dinklage, to take out mutants only to have that plan backfire and kill anyone and everyone on Earth. This time, it's Logan that goes back into the past. This is the logical writing strategy for the Marvel Cinematic Universe because he existed in both time lines and jumping his consciousness into his own body from the "good old days" would be the best strategy.
In this sequel, the actors from "X-Men: First Class" and the original three films starring Patrick Stewart, Ian McKellan, Jennifer Lawrence, Halle Berry, and more combine forces against a common foe. The original trailer features Logan encountering Professor Charles Xavier in a drunken stupor in which he's provided a tale of receiving a message from Logan to send to him in the past about the future of mutant-kind.
In the past, it appears that the events took place after the Cuban Missile Crisis encounter where all ships pointed their guns at the mutants on the island to stop a war from happening. Apparently, this treachery made Magneto declare war on the humans, but at this point he's locked up deep below the Pentagon and Logan enlists the assistance of Pietro Maximoff to partake in a jailbreak in order to free Magneto. Apparently, his incarceration was due to his participation in the JFK assassination. Information there can be found at the Bent Bullet website.
"X-Men: Days of Future Past" opens in theaters come May 23.
