According to Hollywood Reporter, Marvel is in negotiation with actress Tilda Swinton for the role of the Ancient One.
It would be an interesting choice to be sure, with Swinton being well known for her eccentric, otherworldly qualities. While it could be seen as whitewashing, it might also allow Marvel to sidestep fetishizing Asian mysticism while adding another major female presence in its movie franchise (although Swinton won’t be the lead). I wonder if this means Dr. Strange won’t be traveling to Tibet at all, which may be an actual issue for the studio because a portrayal of Tibet might make it hard for Marvel to push the movie in China.
In any case, this shouldn’t be a difficult role for Tilda Swinton, who’s already played a witch-queen, an archangel, a vampire, and a time-traveling robot from the future in her colorful career.
