James Cameron Explains the Alien Breasts in Avatar

It's actually a highly detailed and well thought-out treatise on the morphology and biology of the Na'vi species in relation to the fauna of the planet Pandora. Just kidding! It's because tits are hot. Says Cameron:

Because this is a movie for human people... Let's focus on things that can create otherness that are not off-putting.

This is a man who knows his audience, clearly. What do Avatar fans want? Prehensile dick tails, big wet cat eyes, and boobs, apparently. But I was curious to see if Cameron was right - if people really would care that much if Zoe Saldana's alien character, Neytiri, were as flat as a chalkboard. So I did a little test:

Yes. Yes they would.
