Fans of Sherlock are familiar with the love-hate relationship between Sherlock and Mycroft Holmes. One minute, Mycroft is calmly watching his brother get beaten by an interrogator. The next, the two brothers are playing a “friendly” game of deductions.
But is there a third Holmes brother in the mix? Maybe. He does not exist in any of Sir Arthur Conan Doyle’s stories, but rather, was invented by Holmes scholar William S. Baring-Gould, and named Sherrinford Holmes. Sherrinford would be older than Sherlock and Mycroft, because ostensibly he would be managing the family’s estate—a role traditionally assumed by the eldest son. He may have been briefly alluded to in “His Last Vow,” when Mycroft says, “I’m not given to outbursts of brotherly compassion. You know what happened to the other one.”
If there was a third Holmes brother on Sherlock, who could play him? Here are some ideas to discuss!
5. Michael Sheen
The co-star of Masters of Sex has a significant fan base, and would bring an elegant presence as Sherrinford that would fit in nicely with the Holmes family. Sadly, though, his busy schedule would most likely preclude more than a cameo appearance on Sherlock.
4. Simon Pegg
The co-creator of the Cornetto Trilogy would be a clever addition to the Holmes family. His humour would provide good chemistry with Cumberbatch and Gatiss – perhaps he could be the goofier brother to the geniuses of Sherlock and Mycroft?
3. Nick Frost.
Pegg’s co-star and co-writer in the Cornetto Trilogy recently played Santa Claus in the Doctor Who Christmas special, so he is now part of the Moffat universe. Besides that, he has a razor-sharp wit and the comedic chops to play a fraternal foil for the Holmes boys.
2. Richard E. Grant.
Grant is the right age to play Sherlock’s and Mycroft’s slightly older brother, is well-known, and also has expert comedic timing. Another Doctor Who veteran, his experience as the villainous Great Intelligence would serve him well on Sherlock.
1. Tom Hiddleston
Last year, a rumour began to spread across the internet that Hiddleston, a good friend of both Benedict Cumberbatch and Mark Gatiss, might be cast as Sherrinford Holmes in Sherlock series four. While Hiddleston is younger than Cumberbatch and Gatiss, Sherrinford is supposed to be the eldest of the three Holmes brothers, which might work against him being cast. In addition, coordinating the schedules of three very busy lead actors could prove challenging. But if Hiddleston did join the cast of Sherlock, it would undoubtedly thrill many fans of the show.
