Philippe Roullier is a French actor and voice director, born on January 31, 1956, who is extensively active in the dubbing of Japanese animation. His path to voice acting began in live performance; he started theater at the age of fifteen and enrolled in the conservatory of dramatic art in Grenoble. He later studied at the INSAS (Institut Supérieur des Arts) in Brussels for two years before moving to Paris in 1980, where he continued his theater career for over a decade while also taking on roles in television and film. His transition into dubbing occurred after a director spotted him in a play, leading to invitations to work on films and introducing him to the world of voice-over.

In the field of animation dubbing, Roullier has built an extensive and diverse filmography. He is particularly recognized for his long-standing role as the voice of Jet Black in the acclaimed series Cowboy Bebop. He has also voiced numerous other prominent characters across a wide range of series, including Shinya Otaki in Fullmetal Alchemist, Marude Itsuki in Tokyo Ghoul, and Vector the Crocodile in various Sonic the Hedgehog video games and the animated series Sonic Boom. The breadth of his work includes the roles listed in the query: he voices Spriggan in The Ancient Magus' Bride, Kurokawa in Sabikui Bisco, and La Salamandre in Super Crooks.

Beyond performing, Philippe Roullier has had a significant career as a voice director. He is the voice director for the long-running French dub of the iconic anime One Piece, a series he discovered and grew attached to through his work, directing over 475 episodes. In this role, he also lent his voice to several characters, including the pirate king Gold Roger and the warlord Bartholomew Kuma. He values the freedom and inventiveness that voice acting in animation allows, and he approaches his craft with the philosophy that one must be an actor first before becoming a voice actor. An advocate for his profession, Roullier has spoken publicly about the challenges posed by artificial intelligence to the voice-acting industry, emphasizing the irreplaceable human element in performance and the need for protective legislation.
