Here are a couple of behind-the-scenes videos about the making of Paranorman, the new stop-action-animated horror comedy that opens Friday.

The first video explores the little-known process for making a modern stop-motion animated movie. It’s pretty interesting. The sets are enormous and exquisitely detailed. And wait until you see the “insane” process for making and changing facial expressions.

The movie, from the same team that created Coraline, is about a little boy who can see and interact with the dead. He has to save the day when a 300-year-old curse threatens to destroy his call by unleashing zombies upon it.

Kodi-Smit McPhee, Anna Hendrick, Casey Affleck, Leslie Mann and Elaine Stritch are among actors who provide voices for the movie, which was made by LAIKA.

In one fun video, the voice cast and creators talk about the zombies, which they have conflicting ideas about. The director, Chris Butler, says “they’re just fun,” but the producer and lead animator has deep thoughts about the meaning behind zombies, which he calls a “metaphor for the inexorable march of death.”

That is why he hates the “fast zombie movement.”

Anna Kentrick, for her part, poo poos the whole discussion about whether zombies should shamble or run.

“I don’t know if that’s a debate worth having,” she says, “because then you get into how real the concept is.”

Clearly she doesn’t think it’s very real.

The PG-rated Paranorman opens Friday in 3D ands 2D.
