But writer Diablo Cody - who penned the upcoming horror movie as a follow-up to Juno - recently explained other aspects of the flick.
"This is a horror movie. Not to sound like a pretentious douchebag, but it's a horror movie made by filmmakers, by people who genuinely love film," Cody said to ShockTillYouDrop.com on the Vancouver set.
"Karyn Kusama is a total horror geek, I'm a horror geek, the producers are into this stuff. This was not a mercenary effort to make it seem like something that fit a profile.
We wanted to make a horror movie and we're totally respectful of the films that come before us and I think people will see that in the finish product."
