It must be tough to cast the face characters at Disney theme parks these days. You really need someone who matches the body type and facial features of the original character (whether animated or live-action), but with non-discrimination policies and the possibility that there are simply no suitable candidates applying for the role, compromises are necessary.
Fortunately, Walt smiled on the casting director one day. In my opinion, this young lady was born to play Tinker Bell. She may not be an exact match for the animated original, but she certainly captures the spirit of the character.
