Sherlock And Joan Put Their Powers Of Deduction To Use In These Cool ‘Elementary’ Promos September 20, 2012 Elementary, News We’re just a week away from the premiere of Elementary now, and I don’t know about you, but the anticipation is starting to get to me. CBS’s take on the classic detective Sherlock Holmes and his partner John Watson looks poised to bring some cool new twists to the story. First and foremost of which is turning John into Joan, Sherlock’s sober companion. To tide you over until next Thursday and to give you better idea of Elementary‘s tone, I have four promo vids to share with you below. The first one features Joan’s first encounter with Sherlock’s particular brand of eccentricity (and his wall of televisions). Then the second promo gives us a look at Sherlock’s powers of deduction in action. “I don’t guess things, I observe and then I deduce,” he says. The third promo shows off the show’s sense of humor as Joan teaches Sherlock a few techniques to keep himself awake. The chemistry between stars Lucy Lui and Jonny Lee Miller is on full display in the video, as is the more whimsical side of Sherlock as he cracks a joke about being slapped by an affronted woman he accused of murder. In the final video, Lui and Miller give their own takes on their respective characters and Joan and Sherlock’s friendship. Since Joan was hired by Sherlock’s father, there is initially a bit of distrust there, but as Lui puts it, Sherlock will eventually realize that she is his “ally.” Check out all four promo vids below and let me know if you’re excited to see Elementary in the comments! Elementary premieres Sept. 27 at 10/9c on CBS.
