While Dev Patel was one of the more decent actors when it came to the movie, I don't think he truly captured the essence of Zuko in full.

So, who then would be a fitting replacement?

I nominate Dante Basco, himself. He is a talented actor on his own, he already knows the character since he performs Zuko's voice, and his own blog has stated that he would have loved playing the part for TLA. He is also still plenty young enough as far as looks go to pull off the teenaged Zuko.

I agree. Dante would be a lot better. I just watched Hook again the other day and he was amazing as Rufio. Dante needs better acting roles.

Although, when I found out that Jesse McCartney was cast as Zuko, I was kind of intrigued as to how he would play the part and how he would look with the scar.

Either of these two would work, I think.
