According to The Hollywood Reporter, actress Tilda Swinton (Snowpiercer) is close to finalizing a deal with Marvel Studios to play The Ancient One in Doctor Strange.
The Ancient One is Doctor Strange's mentor and the previous Sorcerer Supreme, and also the one who trained the film's rumored villain, Baron Mordo.
If a deal gets done, Swinton will be mentoring Benedict Cumberbatch's Doctor Strange. It will also mean that The Ancient One will be going through a gender swap as the Ancient One is male in the comics.
The Doctor Strange film will star Benedict Cumberbatch as Dr. Stephen Strange, a surgeon who loses the use of his hands and turns to magic in an effort to repair the damage.
Doctor Strange is scheduled to begin filming this November and will open in theaters November 4, 2016.
