Speaking with Screen Crush, Tilda Swinton confirmed that she and Marvel are past the talking stage and that the deal is finally done for her to play The Ancient One next year in Dr Strange .
“… I just really liked the premise of this and the idea of playing this character. I’m a Marvel fan and I think this particular world that ‘Doctor Strange’ goes into is really, really, really exciting. I’m really interested as both an actor and a fan to see what’s done in this particular world. It’s all about creativity. It’s not about everything exploding at the end. It’s about something very different.”
Swinton wasn’t be phased by the multi-picture deal.
“It’s like a family thing. Who knows where one might pop up. I don’t know where they’ll use me and I don’t know that they know, necessarily, even though they seem to know what they’re doing for the next decade. I think it’s like holding onto the tail of a galloping horse at this point.”
The Ancient One in the comics is a Tibetan mystic who teaches Dr. Stephen Strange the mystic arts with the goal of training him to become the Sorcerer Supreme. The character is traditionally depicted as an old man, but Kevin Feige has already confirmed that they’re changing the origin story.
