Hunger Games-fame Sam Claflin is the latest addition to the already stellar cast of the film adaptation of the Enola Holmes books.  

Starring Millie Bobby Brown, Henry Cavill, Helena Bonham Carter, and Fiona Shaw, the film, bankrolled by Legendary Studios, is based on Nancy Springer's book series, which began in 2006.  

The story revolves around Enola (Brown), the much younger sister of Sherlock (Cavill) and Mycroft Holmes who turns out to be a highly capable detective in her own right. Carter will be playing Enola's mother.
   
Fleabag-director Harry Bradbeer is set to helm the film from a script by Jack Thorne. Millie Brown and her sister Paige Brown are co-producing the film through their banner PCMA Productions.
