According to Unreality TV, even series creator Mark Gatiss has previously expressed interest in casting the actor in the show.

Gatiss said that he is willing to go to extreme lengths in hopes of casting the actor for "Sherlock" Season 4. This led to speculations that Hiddleston will be playing the role of Sherlock's third brother, Sherrinford.
