Talking to Entertainment Weekly, Grahame-Smith said,
After I had turned in the book, I was having a meeting with someone and described Pride and Prejudice and Zombies and he said, "You know, I think there's a script out there called Pride and Predator." It had been languishing in development for years or something. And then, of course, we're all excited about the heat and the Internet buzz about Pride and Prejudice and Zombies and, lo and behold, Sir Elton [John] swoops in. But I don't feel it lessens our chances. For every Dante's Peak there's a Volcano. For every Step Up there's a Stomp the Yard. I say the more mangling of literary classics the merrier.
Part of his positive attitude comes from the difference he perceives between the two projects:
In theirs an alien crash lands and starts picking people off. In ours, there's this zombie onslaught that's been going on for years and Elizabeth Bennett has spent her whole life training to become a highly efficient killer of the undead, as has Darcy. It's more about a love story between two headstrong independent zombie slayers.
Jane Austen would be so proud. Potentially.
