Rodriguez vs. Sigourney in 3D

In the future, on the planet of Pandora, a place populated by humanoids, Earth-dwellers will be deposited and left to fend for themselves.

This will prove problematic for them, and some seriously computer-generated battles will most likely go down.

That's the rough plot of Avatar, the latest supersized film from Titanic director James Cameron, which will star lesbian fave Michelle Rodriguez, Sigourney Weaver, Zoe Saldana, and Giovanni Ribisi.

And because technology is more fun to talk about than who plays human and who's merely humanoid, the film is being shot in a new digital 3D process that will make this grand-scale adventure pop off the screen like no movie before.

Look for the action to leap into your lap sometime in 2009.
