The last few days have been insane for Initiates -- fans of "The Divergent Series." First we found out that the final two movies in the series would be getting new names, "Allegiant" and "Ascendant," as well as sneaking a peek at some sweet logo art. Then we got your first look at the set with Shailene Woodley and the rest of the cast. And then we got the first ever trailer for the movie.

It's so much stuff, that we're practically climbing the walls with excitement! And that's exactly what a key scene in the trailer showed off, as Tris (Woodley) and company scale the walls surrounding the ruins of Chicago in a bananas action sequence, finally showing off the world outside the Windy City.

But how exactly did they pull that all off? To find out, we talked with the cast about scaling walls, falling in love, and what it's like to join a blockbuster movie series already in progress.

Hey, how about we watch that ridiculous stunt on an infinite loop, shall we?

"The Divergent Series: Allegiant" hits theaters on March 18, 2016.
