Ever since Mycroft Holmes made reference to “the other one” in the Sherlock series three finale, Tom Hiddleston has been top of many fans’s lists to play the previously unknown third Holmes brother should he ever appear in the series.


The Thor star has just the right blend of eccentric Britishness, quirky good looks and on-screen intensity to convince as Benedict Cumberbatch’s second sibling.

And it seems Sherlock co-creator Mark Gatiss – who also happens to play Mycroft in the BBC detective drama – agrees, admitting “Tom would be wonderful in Sherlock”, but adding “I’m sure but he only does movies now. What can I say?”

“I’ll ask him if you like,” Gatiss told an audience at a recent Q&A in Brazil, continuing (with tongue firmly in cheek), “Well it’s an internet rumour so it must be true. We might as well just wait and see what happens.”

Sir Arthur Conan Doyle’s original Sherlock Holmes stories make no reference to a third Holmes brother but Gatiss’s character told Sherlock at the end of final the episode His Last Vow “I’m not given to outbursts of brotherly compassion. You know what happened to the other one.”
