Alexandre Gillet is a French actor born on October 17, 1967, who is primarily known for his extensive work in dubbing for French-language versions of films, television series, and animated works. His career is distinguished by his status as the official French voice for several prominent international actors and iconic animated characters.

Gillet's voice is widely recognized in the world of animation and video games. He has been the definitive French voice of the character Sonic the Hedgehog since 2003, a role he has reprised across numerous series and games, including Sonic X, Sonic Boom, and Sonic Prime. He is also the voice of Spyro the Dragon in the French versions of the video games.

Within the specific realm of anime, Gillet has lent his voice to a diverse range of characters. In the popular series Jujutsu Kaisen, he voices Noritoshi Kamo, a role he also reprised for the film Jujutsu Kaisen 0. He is the voice of Jean Jacquemond in the Netflix anime adaptation of Spriggan. He also voiced the character Hunter Harris in the French adaptations of the classic anime series Eagle Riders and Gatchaman II. Other notable anime roles include the complex Tetsuo Shima in the landmark film Akira, the effervescent Leeron in Gurren Lagann, Abe Seimei in Onmyōji, and Adam in SK8 the Infinity. His work also extends to OVAs and films such as 3x3 Eyes, Armitage III, and the Ranma ½ films.

While Gillet's anime roles are varied, he does not appear to have a recurring collaboration with a specific Japanese director or animation studio in the way he does with live-action actors. Instead, his work in anime, as in other fields, is marked by its consistency and range within the French dubbing industry. His most notable and recurring collaborations are with live-action actors, for whom he is the regular French dubbing voice. These include Elijah Wood (Frodo Baggins in the Lord of the Rings and The Hobbit trilogies), Ryan Gosling, Chris Evans (Captain America in the Marvel Cinematic Universe), and Ben Foster, among others.

One of Gillet's most significant achievements is his long-standing and prominent role as the French voice of Sonic the Hedgehog, making him the signature voice for the character for over two decades. His work as the voice of Frodo Baggins in Peter Jackson's acclaimed The Lord of the Rings trilogy is another major highlight, bringing a beloved character to French-speaking audiences. His selection for this role by Peter Jackson himself underscores his standing in the dubbing profession. With a career spanning decades and a filmography that includes hundreds of roles across live-action dubbing, animation, and video games, Alexandre Gillet is a highly respected and established figure in the French entertainment industry.
