MTV visited the set of Divergent a few weeks ago, and in a just-released video report from Chicago they give us a detailed glimpse into the making of the book to film adaptation.

Notably, this Divergent movie set report shares footage of Shailene Woodley (Tris) and Theo James (Four) working together in training scenes on a rooftop. In this section of the storyline there’s still tension between the two characters.

In interviews Woodley and James speak about their characters’ personalities, and there’s a fun moment where the latter actor surprises Woodley. It’s clear they have great chemistry both on screen and off.

Divergent author Veronica Roth is also interviewed because she was on the set that day. Roth speaks briefly about a couple changes between the book and film. She says that while the core of the book is in tact, there are some moments that happen in a different order than they do in the book. Roth didn’t provide specific examples.

Divergent will hit San Diego Comic-Con this Thursday and Hypable will be there to cover what the cast and crew have to say about the highly-anticipated book to film adaptation. We’ll also be going one-on-one with several of the Dauntless members so we can learn how they feel filming went.

Divergent opens in theaters March 21, 2014.
