For the last few years, Millie Bobby Brown (best known for her work on Stranger Things) has continued to work with Netflix on the Enola Holmes movies. Based on author Nancy Springer's The Enola Holmes Mysteries, the Netflix movies feature Brown as the teenage sister of Sherlock Holmes (who is already a famous Victorian-era detective) and government official Mycroft Holmes. While the second movie was not inspired by one of Springer's stories, it earned the same level of success as its predecessors, with both ranking as two of the biggest original film releases in Netflix's history.
