"[Smoking] was really hard," he told the publication. "Filterless rollies, just take after take after take. I gave myself nicotine poisoning three times. When you have to smoke a lot, it genuinely is horrible."
Although the Doctor Strange star's health suffered as a result of his method acting, Benedict maintained it was essential to the role's essence and stressed how he wanted to submerge himself in the character both in front of and away from the camera.
"I wanted that layer of stink on me. I wanted people in the room to know what I smelt like," he continued. "It was hard, though. It wasn't just in rehearsals. I was going out to eat and meet friends of [director] Jane [Champion] and stuff."
