I have watched by chance Kung Fu Panda 2 last saturday (didn't watch the first 'opus' so far).
The similarity between the movie characters ( the Panda and its crew, even with very minor changes) and the characters created by Terry Dunn is obvious to me.
Moreover, there is the 'inner peace' Taichi like dance we can see in the movie:
1. first scene (Panda's sifu)
2. second scene (I am Po)
3. third scene (last battle)
First, I can see an obvious similarity with the Zen-Bear animation but more than that,the last scene is also very similar to the energy ball seen in the Zen-Bear animation.
Since I have not watched the first Kung-Fu Panda movie, I can't say more, but I can suppose that the similarities are even more evident.
It is sad to see how many obstacles Terry Dunn is facing in seeking redress.
