Shes immediately filled with horrible, crushing regret based mostly on fear, Kendrick says.

Luckily, it wasnt just the Bellas who were eager to be reunited in a common cause.

Counteracting any of that over-familiarity on location was new director Trish Sie (Step Up All In).

Its so nice to have fresh blood on set, says Kendrick.

It makes sure were on our best behavior.

When I heard they needed a new director I was just like, Thats it.

I am destined for this,' she says.

It was that crazy, one-sided love affair, but it all worked out.

Fortunately she channeled that crazy affection for the project into zealous drive on set.

She has such positive energy, says Kendrick.

Shes this kind of crazy, lioness woman a real force of nature.

Part of the projects attraction for the director was exploring real emotions and milestones encountered by young women.

These movies are so good at capturing relevant moments that happen to all kids, she says.

The ensemble gets juicier, Sie says.

Especially with Wilsons Fat Amy.

It was funny that Fat Amy chose that name, but is there more?

Where did she come from?

Its been fun to follow those rabbit holes.

Wed do them forever.
