The Sherlock star admits that he is aware of the “very good idea” behind the reappearance of Sherlock’s arch-villain Moriarty at the end of series 3, but says he’s tried to put it out of his mind in order to add to the surprise when he first reads the script. Cumberbatch said that both he and Martin Freeman (Dr. John Watson) like to come fresh to the scripts so they can get a similar thrill to that viewers experience when they first watch the episodes.

Appearing at the San Diego Comic-Con to promote Penguins of Madagascar, Cumberbatch told MTV, “We get a rough idea of where it’s going to go before we get the script.
