"...The mythical Sands Of Time." Looks like Roland Emmerich snuck in to direct a chunk as the titular sands lay waste to the city.
"There are no sand monsters in the movie. For the game, turning everybody in the world except for the two main characters into sand monsters was really useful because it created an inexhaustible supply of enemies for you as a player to fight," explains Mechner.
"But that's a story that's meant to be played with a controller in your hand. And a movie is an experience that's sort of a ride to go on shared by an audience, so we didn't want to make the movie about fighting monsters."
