Netflix has released the first teaser trailer for the upcoming film Enola Holmes, and it looks like good fun. Based on the book The Enola Holmes Mysteries by Nancy Springer, the film puts a twist on the Sherlock Holmes story by creating a sister for the notorious detective. Enola, played by Stranger Things star Millie Bobby Brown, is much younger than her two older brothers but no less gifted. And as if that wasn’t enough, the film finds Henry Cavill playing Sherlock while Sam Claflin fills the role of Mycroft Holmes.
