In an interview for the July 2014 issue of Elle UK, Knightley talks about several things, including her friendship with Cumberbatch. The two, who acted together in “Atonement,” have been close for years — to the point of easy joking.
The “punching” incident occurred after a journalist insulted Knightley. “When I saw [Cumberbatch] again, I said, ‘Did you punch a journalist?’ and he was like, ‘I f***ing did,'” Knightley explains in her interview. “Everybody needs a friend like that.”
Friendship is a good thing too, since Knightley and Cumberbatch will again co-star in “The Imitation Game,” premiering in November 2014.
