Thomas Arnold is a German actor and voice talent. At the age of 13, he was already performing on stage in his hometown of Freiberg. But before he graduated from the Ernst Busch Academy of Dramatic Arts in Rostock, he took a slight detour with an apprenticeship as a patissier. In 1993, while still a student, he won his first acting award at the meeting of German-speaking state drama schools in Vienna. After making his film debut in 1996 in "Zweieinhalb Minuten" (Two and a Half Minutes) by Rolf Schübel, his engagements in cinema and TV films have followed one after the other. Since then, Thomas has been well known to TV viewers through countless appearances - especially in popular crime series. In an ensemble role as forensic doctor Dr. Jonas Zander, Thomas was seen several times alongside Jörg Hartmann, Anna Schudt and Aylin Tezel for the Dortmund "Tatort". Thanks to his work for Volker Schlöndorff's "Die Stille nach dem Schuss" (The Silence After the Shot) in 2000, which celebrated its world premiere in competition at the Berlinale, Thomas has continued to attract international attention. He was cast in smaller roles in Florian Henckel von Donnersmarck's award-winning film "Das Leben der Anderen" as well as in "War Horse - Gefährten" (2010, directed by Steven Spielberg) and also starred in the two hit U.S. series "Homeland" and "Berlin Station," both filmed in Berlin. Schlöndorff called on him again for "Diplomacy" (2013) as well as for the Grimme Award-winning TV production "Das Meer am Morgen".  In 2021, Thomas took on a role in the fourth season of the historical crime series "Babylon Berlin," already eagerly awaited by fans. In addition to his work in front of the camera, he also works as a voice talent, primarily for commercials, documentaries, features, radio plays and audio books, as well as for dubbing.
