Jessica Brown Findlay is an English actress who has contributed to the anime and animation voice acting landscape, most notably through her role in the Netflix animated series Castlevania. Her performance background includes training at the Central Saint Martins college in London, and she developed her stage presence from an early age, having joined a local performing arts company at fourteen where she honed her skills in dance, singing, and live performance. These foundational experiences in musical theatre and drama preceded her transition to on-screen and voice acting work.

Within the realm of voice acting for anime-influenced Western animation, Findlay is best known for her portrayal of Lenore in the Netflix series Castlevania. Lenore is a major character introduced in the show's third season, serving as a diplomat for the Council of Sisters, a group of vampire queens ruling Styria. Unlike the more physically imposing members of her council, Lenore is characterized by her strategic mind, diplomatic finesse, and complex manipulation of Hector, one of the series' forgemasters. Findlay voiced Lenore across multiple episodes of the series, appearing in seasons three and four, which constitutes a recurring and significant role in the show's ensemble cast.

In terms of recurring professional collaborations, Findlay has worked with actor Jason Isaacs on multiple projects. According to voice acting credits and collaboration tracking, Isaacs is the performer she has teamed up with most frequently, appearing alongside him in three distinct titles. This professional partnership is exemplified by their work together on Castlevania, where Isaacs voiced The Judge, a key character in the same season that introduced Lenore. While Findlay has a background primarily in live-action film and television, her voice work on Castlevania remains her most prominent contribution to the animated and anime-style genre, and the series represents the core of her recognized achievements in voice acting.
