a movie would be great, though i think it should be animated as it is not as expensive, i guess they could bring back some of the voice actors like the girl who voiced katara(dont remember her name) i doubt her voice changed much since she was a late teenager/early adult who had voiced katara. gray desilie(ahh cant spell) can revoice azula, danta bosco can still voice zuko, saw his latest interview, his voice has not really changed at all. jessie flower or somthing like that can still voice toph, saw her did voice reacatment for toph and is still the same as some years ago(she is not incuded in the search.), pretty much, most of the voice actors can still voice some of the older characters exept the voice actor for aang who's voice might have already deepened since he last voiced aang. i am saying, if they wanted, they could bring back most of the voice actors if they wanted to. i really dont think that a movie is happening animated or otherwise since the creators had already confirmed that they were moving on the other things for the meanwhile.
