The Netflix film starring Millie Bobby Brown as a young detective is Enola Holmes. Brown plays Enola, the teenage younger sister of Sherlock Holmes, who sets out to find her missing mother while becoming involved in a dangerous political mystery.
Released on Netflix on September 23, 2020, the film was directed by Harry Bradbeer and written by Jack Thorne. It adapts The Case of the Missing Marquess, the first novel in Nancy Springer's Enola Holmes Mysteries series. Henry Cavill plays Sherlock, while Sam Claflin portrays Mycroft and Helena Bonham Carter plays Enola's mother, Eudoria.
The movie is not a standard Sherlock Holmes adaptation: Enola is the central investigator, and she frequently breaks the fourth wall to address the audience. Another common mix-up is Nancy Drew, a different fictional teenage detective. Enola Holmes was originally intended for theatrical distribution, but Netflix acquired its worldwide distribution rights during the COVID-19 pandemic. A sequel, Enola Holmes 2, arrived in 2022.
