Tempus Fugit pointed out in the HBO forum a 1Up interview with Peter Jackson about the King Kong game coming out in connection with Jackson's latest film.

There are a few mentions of other games, among them Halo:

I also love the sense of scale and design in games like Halo 2. I found that art direction to be more impressive than most films I've seen. I like to explore and soak up the visual experience. [...] Can't wait for the Halo movie. I want to see Warthogs and Ghosts in the movies. And the Flood.

Jackson also says he has a "soft spot for shooting zombies". I wonder if he'd want to pick up a copy of Stubbs to see how the other half lives...
