Young Sherlock Star & Showrunner Break Down Prime’s New Origin Story [Exclusive]

Sherlock develops a friendship with James Moriarty (played by Donal Finn, known from The Wheel of Time), a clever student who matches Sherlock’s intelligence and mischievousness. This is, of course, the Moriarty who will eventually become Sherlock’s greatest enemy. Initially, however, they connect while solving a mystery, clearing their names after being wrongly accused of a crime, and dealing with Sherlock’s complex family life. Showrunner Matthew Parkhill and actor Louis Partridge discussed their approach to reimagining Sherlock, the growing bond between Sherlock and Moriarty, their casting choices, and Partridge’s feelings about potentially returning to the Harry Potter universe.
