According to the reveal article, Cumberbatch hasn't been in costume very often on set just yet. Filming only began in November, and isn't set to wrap until March, so Cumberbatch took the photo shoot as an opportunity to practice Strange's signature, arcane hand gestures.
"I'm still in the infancy of learning all that," Cumberbatch says. "It was like, okay, I've got to keep throwing these poses, these spells, these rune-casting things, everything he does physically. I'm thinking, there's going to be a huge amount of speculation and intrigue over the positioning of that finger as opposed to it being there, or there. And I'm still working on that. We haven't played any of those scenes yet. I felt really self-conscious. But, then, by the end, it was great. It's like anything, you just have to experiment."
Doctor Strange is directed by Scott Derrickson, with a screenplay by Jon Spaihts and C. Robert Cargill, and stars Cumberbatch, Chiwetel Ejiofor, Rachel McAdams, Michael Stuhlbarg, Mads Mikkelsen and Tilda Swinton.
