Imagine you’re at the end of your life. Now imagine everybody around you thinks you’ve been a Sprite person instead of a Coke person, a V-neck person instead of a crew-neck person — when really, you’re the opposite of those things. Okay, so that’s what Dr. Watson has apparently done to Ian McKellen’s Sherlock in this summer’s Mr. Holmes (just swap in pipes and deerstalker hats). The movie’s official trailer, released Tuesday, reveals those winking misconceptions, as well as an intriguing femme-fatale mystery. (Sadly, still no sign of Patrick Stewart.)
