Thomas Schmuckert is a German actor and voice artist, born in Wuppertal in 1965. He pursued his passion for performance at the Hochschule für Schauspielkunst Ernst Busch in Berlin from 1990 to 1992, following earlier training at a theater seminar in Kreuzberg. His career began on stage, with his first role as Romeo in Romeo and Juliet in 1990, and he has since built a diverse portfolio that spans theatre, film, and television. As a screen actor, he has appeared in numerous German television series, including prominent shows like In aller Freundschaft, SOKO Leipzig, and Bad Banks.

While Schmuckert is an established on-screen actor, he is perhaps most widely recognized by international audiences for his extensive voice work. He has lent his distinctive voice to a vast array of characters in dubbed versions of films, television series, video games, and audio dramas. His voice is characterized as markant and ausdrucksstark, or distinctive and expressive. He is a baritone, is fluent in English and French, and is also a trained pianist and singer.

Within the realm of anime, Thomas Schmuckert has become a prominent and beloved voice. His most iconic role is that of the villain Freezer in the Dragon Ball franchise. He first voiced the character in Dragon Ball Z Kai and has since reprised the role in subsequent films and series, including Dragon Ball Z: Resurrection F and Dragon Ball Super: Broly. He has described Freezer as a schauspielerisch ein gefundenes Fressen, or a gift for an actor, due to the character's wide range, from an androgynous dandy to a brutal despot. He has also voiced the character in the Dragon Ball Super series. His involvement in the franchise has made him a familiar and appreciated figure at German anime events, such as the Anime Berlin Festival premiere of Resurrection F.

Beyond Dragon Ball, Schmuckert has voiced a wide variety of characters in other notable anime productions. He took on the role of Willard in Sirius the Jaeger and provided the voice for Douglas in the critically acclaimed Cyberpunk: Edgerunners.

Other credits include Dr. Kiriko in Black Jack, Rikakos Vater in Ocean Waves, Leiot Steinberg in Strait Jacket, and Seiichi Inoba in Wanna Be the Strongest in the World. He has spoken about the unique challenges and fascinations of dubbing anime, noting the cultural and linguistic differences compared to dubbing live-action content from closer cultures. He also mentioned finding the character of Shibazaki in Terror in Tokyo particularly compelling for his humanity and unorthodox methods.

His voice acting repertoire extends well beyond anime. He is the German voice for actors such as Jason Bateman, whom he dubs in the series Ozark, and has also voiced Esai Morales in Mission: Impossible – Dead Reckoning and John Dagleish in the 2023 version of The Little Mermaid. He has also provided voices for video games, such as the character Daruk in The Legend of Zelda: Breath of the Wild and its prequel.

In addition to his on-screen and dubbing work, Schmuckert is a highly active voice artist in the German audio drama and audiobook industry. He has narrated numerous audiobooks and played leading roles in popular series. Notably, he voiced the title character in the horror series Dorian Hunter, a role for which he received the Hörspiel Award for Best Speaker.

Throughout his career, Thomas Schmuckert has also been deeply involved in the acting community.
