I understand that the Ancient One is just a character that can technically be played by anyone whether male or female. My only gripe is that an opportunity to cast a possible Asian actor or actress presented itself and Hollywood decided to cast a caucasian female instead. According to the comics, the Ancient One originated from the Himalayas so one would think let’s cast someone similar to that geography. Of course many movie adaptations do not copy everything from the original source material but it would have been a nice tribute to the creators that created the character. I am sure Tilda Swinton will put her own creative spin on the Ancient One so it will be interesting to see how it will play out on the big screen.
Marvel issued a statement at that time, saying that the Ancient One “is a title that is not exclusively held by any one character, but rather a moniker passed down through time, and in this particular film the embodiment is Celtic.”
