With scribes of the popular detective series on board and a similar format to that of "Sherlock", some were quick to assume their latest collaboration to be a potential series involving a crime-solving vampire, reported Digital Spy.
At a screening of the latest episode of "Doctor Who" at Cardiff's BBC Hoddinott Hall, Moffat quipped about the possibility.
"Dracula solves crimes!" he said, before adding, "I just made that up - it's not that, it's not that!"
Moffat also revealed he and Gatiss would not start working on the project immediately.
