Looking for an Ian McEwan anecdote...

...there is some Ian McEwan interview, and I believe the interviewer was a women, where he mentions that Joe Wright (director of the adaptation for Atonement) actually apologized to him for messing up the ending of the novel. McEwan say's that the film's ending is terribly sentimental, or something like that. In any case, if any of you know off-hand which interview this was in, I would be grateful
