The estate has named Netflix, Legendary Pictures, screenwriter Jack Thorne, director Harry Bradbeer and publishers at Penguin Random House, among others, in the lawsuit.

The estate’s executives are seeking a trial and unspecified damages also relief from further infringement on copyrights. So far there are no new updates on whether the legal proceedings will delay the release of the film version or not.

As planned, Enola Holmes is slated to premiere on Netflix in September.
