Sir Arthur Conan Doyle’s estate has sued Netflix for copyright infringement over its upcoming Enola Holmes film starring Millie Bobby Brown.

Axar.az reports citing foreign media that the movie features the 16-year-old Stranger Things actress as the exceptionally gifted younger sister of famed detective Sherlock Holmes, created by Sir Arthur.

It is based on the Enola Holmes series of books, written by US author Nancy Springer, who is also being sued alongside her publisher Penguin Random House and producers Legendary, among others.

As well as British actress Brown, Enola Holmes also stars Henry Cavill as Sherlock and Helena Bonham Carter as his mother.

It will be available to stream on Netflix in September.
