The 13-year-old actress just signed with Legendary entertainment to star as Enola Holmes, Sherlock's sister, in a film series based on Nancy Springer’s Enola Holmes Mysteries novels.
Not only is she going to star in this multi-film deal but Millie will also be producing the mystery films.
In the series, Sherlock is already a famed detective while Enola, 20 years younger, is still at home being raised by their mother. That is until mom suddenly disappears, and it's left to young Enola to solve the mystery...
Sounds amazing, I wonder if a Demogorgon will make an appearance?
