Castlevania is an American adult animated dark fantasy action streaming television series made for the streaming service Netflix and is produced by Frederator Studios' Kevin Kolde and Fred Seibert. Based on the Japanese video game series of the same name by Konami, the first two seasons adapt the 1989 entry Castlevania III: Dracula's Curse and follow Trevor Belmont, Alucard and Sypha Belnades as they defend the nation of Wallachia from Dracula and his minions. Additionally, characters and elements from the 2005 entry Castlevania: Curse of Darkness are featured beginning in the second season, and Alucard's backstory is drawn from Castlevania: Symphony of the Night. The art style is heavily influenced by Japanese animation and Ayami Kojima's artwork.
The series was originally planned as a film, developed by producer Kevin Kolde and his company Project 51. Kolde had a contract for a script with writer Warren Ellis in 2007. The project entered development hell until about 2015, when Adi Shankar boarded the project and it was picked up by streaming service Netflix. Powerhouse Animation Studios joined the team and production commenced. The production team includes staff members who worked in the Japanese anime industry.
The series premiered on Netflix on July 7, 2017, and was renewed for an expanded second season of eight episodes on the same day; the second season premiered on October 26, 2018. A ten-episode third season was greenlit by Netflix and released on March 5, 2020. The series ended with the release of its fourth season on May 13, 2021. The series received positive reviews, with its visuals and voice acting receiving much praise, although the writing, particularly of the third and fourth seasons, garnered an polarized response.
A follow-up series set in the Castlevania universe, Castlevania: Nocturne, is in the works at Netflix which will focus on Richter Belmont, a descendant of Trevor and Sypha, and Maria Renard during the French Revolution.
