Radford estimates Holmes’ IQ at 190, which places him much, much higher than our crazy-haired scientist. Since then, there have been many more studies on this fictional character leading people to lower his intelligence rating, but he still remains one of the smartest characters ever written.

But he was just inclined to the Physics part, no doubt he was a genius, but Sherlock and Moriarty as portrayed in the Series and the Books seem to have higher raw intelligence, so on that note, their IQ might be some more than 160.

Eurus Holmes is described by Mycroft as an era-defining genius beyond Newton. Newton is estimated to have an IQ of 170–200. So Eurus must have an IQ above 200. Marylin vos Savan is a real person and has measured an IQ of 228.

Enola Holmes is actually Sherlock Holmes’s sister. Her brothers, Sherlock and Mycroft, are also in the movie—obvs—although Mycroft existed in the Sherlock canon going all the way back to the original Sir Arthur Conan Doyle stories.

Though many viewers felt the chemistry between Enola and Lord Tewksbury in the film, the character is not present in any of the five subsequent novels in the series. Enola does not get married in the book series.

Benedict Cumberbatch has revealed that his character Sherlock fell in love with Irene Adler in ‘A Scandal in Belgravia’. The 35-year-old spoke about the challenges of shooting the episode, confirming that Sherlock was charmed by Irene and ultimately fell for her over the course of the instalment.

Benedict Cumberbatch has spoken about his character Sherlock Holmes’ sex life, saying that he is no longer a virgin. The actor, who plays the famous detective in the popular BBC series, told Elle that although it was implied that Sherlock is a virgin in the premiere of the second series, this may no longer be the case.

Adler was just a necessary sacrifice. Think about it this way. Moriarty had to hurt Sherlock. He couldn’t do it physically, because then the movie ended in few minutes.
