Diablo lets her little demon out

Screenwriter Diablo Cody’s copy of the Oscar Winner’s Playbook has apparently gone missing. The Academy Award-winning “Juno” scribe follows that success (and her critically praised Showtime series “The United States of Tara”) with a horror movie, “Jennifer’s Body” (opening Friday), about teenage BFFs played by Megan Fox and Amanda Seyfried (who have a makeout scene -- maybe this is the perfect post-Oscar project after all) whose friendship is tested when one is possessed by a demon. Worst-date-ever murders ensue.

When did you write this?

Before “Juno” was filmed. I had written something uplifting, and I wanted to do something darker. There are no sing-alongs in this film.

You’re in the bar scene before the fire, but we don’t see your death.

I was actually involved in a pyrotechnic stunt, but it got cut. My acting is terrible, to be frank. We had to be content with the one shot of my face.

Aren’t you afraid this could lead to a trend of false diagnoses of demonic possession?

I would feel proud. It’s already wonderful being blamed for the teen pregnancy epidemic.

Can you think of a movie so scary it practically traumatized you?

One of the first horror movies I ever saw was “Poltergeist.” I’m telling you, that movie would not be rated PG now. I mean, a guy rips off his face. It was more than I could handle at 7 years old. I didn’t sleep for a long time.

You’ve talked before about this being a different approach for a horror film -- how so?

I think tonally, the film is complicated. In test screenings, people were asked to write down “What other movie does this remind you of?” -- for marketing purposes. And so many people wrote, “Nothing. I have never seen another movie like this.”

--

I’d take that as a compliment.

I think it made some people nervous, but it made me very happy.
