After muttering about how an AVATAR franchise would make sense and hinting that there could be a trilogy of AVATAR films, James Cameron has confirmed that there will be an AVATAR sequel, fueling speculation about how it might top the original.
Things we do know: There are two planned sequels but they won't be one continuous story, they'll be self-contained. They'll also follow Jake and Neytiri. It could take place around a different moon of Polyphemus this time, although producer Jon Landau has already hinted about exploring Pandora's interior. Some bloggers guess that James Cameron, famously obsessed with water, has an amazing underwater environment mapped out for Pandora. There are also different Na'vi tribes that call the planet their home and we never really got a sense of how intra-species politics work between the different tribes. Cameron confirmed he’s mapped out what will happen in the sequels, although he hasn’t written any scripts yet.
The good news? The sequels won't take four years to make. Cameron has said he can get them out faster than the first AVATAR.
Also, when Jake's avatar and Neytiri have sex, you see only a small amount of alien petting. After all, it's a movie about blue creatures, not a blue movie. But there was a larger sex scene that was filmed but then cut, and Zoe Saldana hints that it had something to do with syncing the two participants' ponytails. Of course, if the Na'vi use hair-syncing both for sex and to communicate with everything else on Pandora, you get some pretty squicky issues. Still, Zoe Saldana says, "We had a lot of giggles there" during filming.
You'll be able to see it on the DVD, and when you finally get your mind out of the gutter, there'll be another 10-minute scene of Jake going through a trial to gain membership in the tribe: the hunt for a rhino-like sturmbeest.
