I know he [Julian Assange] is a man of fierce determination, and now living under the strain of house arrest in the Ecuadorean embassy as a "political exile," as he calls himself.

It's an interesting arc. You start with a character [Doctor Strange] who's likeable and charming but very arrogant and distant. He's funny but you can see there are massive holes in his life. It's a very painful transition and all that he becomes is tested so quickly and violently.
