Father Z was there! An on-the-spot report.

In fact, the audience tonight was very responsive. They burst into applause when the baby Jesus was born, as one might expect, and laughed at the appropriate moments of comic relief, provided not terribly subtly by the three Wise Guys, er um, Men. In fact their humorous repartee is sets up their glorious expressions of faith at the moment of truth. I was up in the press area and there were some studio nazis from New Line present to make sure no one was recording anything or taking images from the showing. They freaked out when people in the audience began shooting flash pictures of the screen at predictable moments, and began making hurried cell phone calls.

Theological discussion of labor pains and such follows in the comments there.

A news report. 8,000 in attendance:

Proceeds from the Vatican benefit premiere will go to the building of a school in the Galilee village of Mughar which will be attended by Druze, Christian and Muslim children.
