New X-Men Days of Future Past clip reveals how Charles Xavier can walk

The trailers and photos for Bryan Singer's X-Men: Days of Future Past shows young Charles Xavier (James McAvoy) both walking and in a wheelchair. This led fans to wonder how the famously crippled mutant, who took a bullet to the spine at the end of X-Men: First Class, could be upright. A new clip for the movie provides the answer.

So Charles gave up his powers in order to be able to walk again. It seems like a bit of a convenient explanation, but we'll have to wait until the movie comes out on May 23 to understand the full scope of the situation.

In other news, a recent television spot for X-Men: Days of Future Past showed Quicksilver (Evan Peters) with a young girl, which caused some fans to assume the girl was his sister, Scarlet Witch. But according to director Bryan Singer, those fans guessed incorrectly.

Singer, who is not doing any more promotions for the movie due to the sexual abuse allegations against him, spoke to Empire Magazine (via Comic Book Movie) recently and revealed that he actually cut Quicksilver's sister from the movie.

"Is that the Scarlet Witch? No, that's his little sister," Singer said. "I even had a line which I cut, where Quicksilver's mother says to the little girl, 'Go up and bug your sister,' and the little girl says, 'She bugs me!' You never see the older sister, but it was to imply that there is an older sister for comic book fans. I ended up cutting it."

It remains unclear at this point if Scarlet Witch would be introduced in X-Men: Apocalypse in 2016, but Singer also teased that Evan Peters could return for the sequel.

"Even though our Quicksilver is not a main character like in The Avengers, it's a character there's a lot of thought and concern about and it's a character I'd like to explore further in the sequel," he said.
