Continuity mistake: When Sherlock is backstage at the circus and finds the yellow spray paint, he draws a line on the mirror. In the next shot, the line he drew is completely different (and in fact is more of a squiggle). (01:07:40)
His Last Vow - S3-E4
Other mistake: The helicopter that takes Sherlock and Watson to Magnussen's house is the same one Mycroft arrives in later. Tail number G-VGMG.
Continuity mistake: In the opening scene when John is going to the refrigerator, a white skull can be seen on the left side of the kitchen table amongst all Sherlock's science equipment. When he closes the refrigerator door again after discovering the severed head, the skull has disappeared. As he's leaving the kitchen, the skull reappears. (00:03:25)
His Last Vow - S3-E4
Continuity mistake: When Sherlock is being rushed to the hospital, when the paramedic rips open his shirt the body has body hair, but all the topless scenes following show that Cumberbatch has a hairless chest.
Continuity mistake: When Sherlock pulls the gun on Moriarty in the pool scene, he is holding it with two hands but then puts one hand down. In the next shot, he has two hands on the gun again. Then again in the next shot he only has one hand on the gun.
Continuity mistake: After Sherlock repeatedly tells Culverton that he doesn't want to die, in the closeup Culverton increases the dosage with his right hand, but when it cuts to the wideshot he's doing it with his left hand.
A Scandal in Belgravia - S2-E1
Continuity mistake: At Buckingham Palace, Watson has just sat down next to Sherlock. There is a red pillow between then on the couch. It moves, sometimes sitting straight and sometimes tilted, between shots throughout the scene. (00:14:45)
Continuity mistake: When Sherlock goes to look out the window at John leaving (after the tiff about the head in the fridge), his dressing gown is hanging off his right shoulder, exposing his t-shirt. Next there is a wider shot of him from behind, and his dressing gown is on straight, covering both shoulders properly. Then there's another closeup and it's off the right shoulder again. (00:05:40 - 00:06:10)
Continuity mistake: Sherlock is dancing with the bridesmaid towards the end. When they stop and are talking with Watson, Sherlock's hands keep switching from being behind him to in front of him, depending on the camera angle.
Chosen answer: That line of dialogue has never actually been spoken in any of the Sherlock episodes, during seasons 1-4. However, that line is written in someone's fan-fiction story online, where it's said by Sherlock and directed at Anderson.
