What film properties would make amazing video games?

Howl's moving castle is a great setting for an RPG, so is Castle in the sky.

Event Horizon and Pandorum are good for Dead space style horror sci-fi

Serenity / Firefly is a good setting for the next Mass Effect style game. Notch already wants to use it for the next Elite type sandbox space game which could be even better.
