It has always struck us as strange that James Cameron's next two movies are "Avatar 2" and "Avatar 3." Far be it for us to stand in the way of a guy trying to make a buck or a billion, but so much of James Cameron's passion seems to be driven by risk. This is a man who needs to be out on that crazy limb, with everyone predicting disaster, only to pull a miracle out of nowhere. And there isn't much that's less of a risk than "Avatar 2."

Or so we thought. Michelle Rodriguez, who was in the first film even though we totally forgot about her character, says that "Avatar 2" -- which she may or may not be in -- will take place underwater.

This makes sense: Cameron's a deep-sea diver adventurer sort, with the "Aliens of the Deep" and the "Sanctum," so it of course jibes that he'd want to get back in the tank for the next "Avatar." But, uh, maybe James doesn't remember from "Titanic," but making movies in water is really, really hard. And extremely pricey. There's your risk: There's your crazy messianic James Cameron movie. Let's do it in water.

So let's see: This is a sequel, directed by James Cameron, in 3-D, taking place underwater. All he has to do is cast everyone in "How Do You Know," and this will be the most expensive movie of all time. Awesome!
