Pierreson is set to play a new, darker version of Dr. Watson. So far, he's built a steady career alternating between TV and movies, including roles on both Death in Paradise and Line of Duty. He also appeared in Netflix's The Witcher as Istredd, and he has something in common with one of his co-stars: like Darci Shaw, he had a role in the film Judy.
