@easton422 They could just film it as normal, and then edit her eyes after filming to make her seem blind. I’m pretty sure they won’t used an actual blind actress.
Although, given the current trend, M. Night Shyamalan may also very well just change Toph and make her not blind, of perhaps extremely buff, and make her a tough male character, since tough sounds like toph.
Given the current situation, it has already been 2 years and fans of ATLA have still not calmed down over the so-called ‘error in continuity’ between ATLA. Chances are, there won’t be a sequel, and if there was, it won’t be by M. Night Shyamalan.
I really do want M. Night Shyamalan to finish the trilogy though.
