Though "" already has its foe in Lord Blackwood, the Guy Ritchie-directed movie apparently won't leave the famous detective's arch-nemesis, Moriarty, out of the picture. Talking to IGN at the British Independent Film Awards, Blackwood's depicter, , hints on the possibility, suggesting that Moriarty will have a small appearance in the film.
"Moriarty's in it," Strong claims, adding, "but you don't really see him. I think he's there because if the franchise carries on, there's a possibility that he will appear in a larger guise." He then adds that his character is still the main villain, saying, "But for the purposes of this one and the detective narrative, I'm the guy that Sherlock's after, Lord Blackwood. And he's a cultist/Satanist lord who is the ultimate cad."
