JPM: Sarah only does a cameo in G2. Was that the plan from the beginning?
SS: We started talking about GRUDGE 2 even before GRUDGE 1 was released in October 2004. And we didn't know what Sarah's availability would be a year off down the road. So her character had some wildly different story arcs in the various scripts we put together -- in one version, she's in almost every scene; in another, she's in about half of the film; in one, she's only in a couple scenes; and in one, she's not in the story at all. Because the circumstances of the production kept changing (when we were going to shoot, what Shimizu liked and didn't liked in the script, etc.) the role of Karen Davis was mutable through much of the development process.
JPM: Personally, I think the trailer revealed too much too soon. What can the audience expect from G2?
SS: I'd have to agree with you there -- though with that exception aside, I think they did a fantastic job with the trailer. It's pretty creepy!
It's hard to answer your question, since I haven't seen the final version of the film. But what I do know is that the film will have LOTS of scares and LOTS of surprises...
JPM: I've always wondered what goes through the mind of a screenwriter writing a horror movie. Where do you find your inspiration in writing scary scenes?
SS: Much of the inspiration I found writing GRUDGE 1 came from the nightmares I had after watching Shimizu's original JU-ON films. I still had some left over, so I used them up in G2. :)
