Following his memorable debut in the wizarding world, Fiennes Tiffin took a deliberate approach to his craft, appearing in smaller projects before landing the role that would define his early adulthood. He achieved international stardom as Hardin Scott in the After film series, a romantic drama franchise based on the novels by Anna Todd.
