“It was Paul McGuigan’s. The very first episode to be shot was The Great Game, the third episode of the first series. And in that there was a lot of texts, and Paul doesn’t like to cut away to phones so he elected to put the text on the screen, which I thought sounded awful. But then, walking past the cutting room, I saw it, and I thought it looked brilliant. At the time, because I’m always very late with my scripts, I was still writing A Study in Pink. And I loved it so much I wrote it in. We used it during the pink lady deduction scene, it displays all the things Sherlock is seeing. So I slightly expanded Paul’s brilliant idea. Now of course everyone’s at it, we all try to find new ways to use text on screen but 99% of the credit goes to Paul McGuigan.”
