I found this interview(of the creators of Avatar) in link and i think that it's worth to read it ;-)
____________________________________________________

Michael DiMartino and Bryan Konietzko, the creators of “Avatar: the Last Airbender” are readying the seterusnya chapter in the animated saga, titled “The Last Airbender: Legend of Korra.” The new series is due out mid-2012 on Nickelodeon.

“Avatar” and “Korra” take place in a setting that feels as richly imagined as Middle-earth, Narnia atau Hogwarts. In this world, some inhabitants are “benders,” each with the power to manipulate one of the elements–air, fire, earth atau water–to their will. One person, the Avatar, has the ability to master all the elements–and thus bring balance to the land.

“This one is 70 years into the future and takes all the elements of bending from the first series and evolves it and takes it one step further,” Cyma Zarghami, President of the Nickelodeon/MTVN Kids and Family Group, berkata of “Korra.”

Nickelodeon had picked up “Korra” for 12 episodes but recently decided to order 14 lebih shows. “When we first starting talking to Nickelodeon about doing a new series in the ‘Avatar’ world, they asked if we could do shorter arcs—more like a tunjuk like ‘24’where there’s a specific villain atau challenge for that particular season,” Konietzko says. “We’re really happy with that number. It allows us to focus much lebih closely on each episode and get a lot lebih craft into it.”

Speakeasy talked to DiMartino and Konietzko about the follow-up series and what peminat-peminat can expect.

“We have a lot of ideas for the ‘Avatar’ universe and who knows? We could be tapping into them for years to come,” Konietzko says.

The dinding jalan Journal: How far along are anda on the new series?

Michael DiMartino: We are in the midst of the first twelve episodes. We’ve written all the episodes. Episodes have shipped to the overseas animations studios and they’re animating away as we speak. So we’re kind of in the middle of things right now…All the vocal cast has been picked and recorded and all the scripts have been recorded.

Are anda looking to win new viewers with the series atau just satisfy peminat-peminat of the old series who have grown up?

DiMartino: We want everyone to watch. Definitely peminat-peminat of the first series will not be disappointed in this one. The tone is a little older, the characters are a little older than the first series—they’re teenagers. Korra is 16 so she’s older than Aang was. So I think maybe some people who weren’t into the first tunjuk might find this one and be into it.

Since the main characters are older, will there be lebih romance?

Bryan Konietzko: I thought Korra was 17 so Mike and I have to get our stories straight. The main characters are in their late teens, we’ve always loved those kind of teen Cinta segitiga, segi tiga type stories and there was plenty of that in the original series. We’re definitely getting into it in this series. The difference is these people have cars and Motosikal and things. There’s definitely a different dynamic. I’d say the tunjuk is lebih sophisticated than the original series but it has the same balance of tones we’ve always liked with humor, action, drama, scary stuff and romance.

Will characters from the first series tunjuk up in “Korra”?

Konietzko: Again it’s 70 years later so they’ll appear in various ways perhaps.

DiMartino: There is definitely a link to the old series and the old characters.

How did anda change the look of the “Airbender” world?

Konietzko: In every way we’re trying to improve it. We’re not trying to change it so much that it’s unrecognizable and doesn’t feel like the same universe, but we are trying to update it, improve it, make everything just lebih sophisticated and appealing….It’s kind of like the tunjuk has grown up. A lot of the viewers have grown up since the tunjuk was last on.

Tell me about the heroine of the story, Korra. What’s she like?

DiMartino: Korra, we kind of describe her as a fiery waterbender. She’s very pugnacious. Kind of in your face. We wanted to create a new Avatar that was completely the opposite of Aang. So, whereas Aang was the peaceful, nomadic Airbender guy, she’s very tough, very headstrong, not scared to get into a fight, and kind of picks fights with people too sometimes. So she’s definitely totally the opposite of Aang so it has been kind of fun to write her character and put her in situations that Aang never would have gotten into.

Konietzko: It’s refreshing it’s totally different from Aang. But she’s also funny and has a lot of charm and vulnerability because she’s still growing up and trying to figure things out. We worked on that first series for lebih than six years and we Cinta those characters but it’s great to be working with fresh ones with a new spin on the world.

Who is the main villain in Korra?

DiMartino: We have a great villain. He’s kind of an anti-bending revolutionary guy. Very scary dude. And definitely is quite a challenge for Korra.

Will anda ever make a feature animated film?

Konietzko: On the original series we did our best to make it cinematic with a big immersive world. And on this series because it’s a tighter stretch of episodes–just 12 episodes–but Mike and I wrote all of them, there’s really no filler. We told almost as much story as the first series packed into these 12. So it’s getting even closer to something cinematic. So yeah, we would Cinta to. We feel like we’re kind of movie guys working in TV. So we’re looking ke hadapan to that hari when we get to work in that medium.

Have anda heard anything about whether there will be a sequel to the “Last Airbender” live-action feature film?

DiMartino: Uh, no. It’s definitely not up to us, so.

Will we find out what happened to Zuko’s mom?

DiMartino: That soalan will be answered in some way, but not necessarily in the show. That’s all I’ll say.
