There is a new trailer for The Last Airbender (which would be called Avatar but it might confuse people) that you can watch at the official site. I would embed it but that is forbidden! It looks to me – and I own all the DVDs so I am some kind of expert – that the film will follow the first series pretty closely. Which is good! You can borrow the series from the library. Not the second and third series though, as for some reason they aren’t available in NZ.
