Are they making a movie form the book beyonders by Brandon mull?

First answer:

"I think so did you watch the video? It might be the trailer"

...Actually, that was a book trailer which means that actors were hired as a promo for the book. As far as I know, that trailer wasn't authorized by Brandon Mull and as the book series hasn't been around longer than 2011-2013, it is unlikely to have a movie made as of yet...but who knows? I'd like to see one made.
