As of April 2026, the cast of Vienna Blood is led by Matthew Beard as Dr. Max Liebermann and Juergen Maurer as Detective Inspector Oskar Rheinhardt. The series, which returned for its highly anticipated fourth installment in late 2024 and early 2025, continues to feature a core ensemble including Amelia Bullmore (Rachel Liebermann), Conleth Hill (Mendel Liebermann), and Charlene McKenna (Leah Liebermann). The 2026 landscape of the show has seen the duo tackle their most dangerous case to date, known as the “Mephisto Waltz” arc, which significantly shifted the show’s format from standalone movie-length episodes to a continuous four-part narrative. This shift allowed for deeper character development and a more immersive look at the political instability of early 20th-century Vienna.
Matthew Beard as Dr. Max Liebermann
The heart of the series lies in the brilliant, Freud-inspired mind of Max Liebermann, played by British actor Matthew Beard.
Character Evolution to 2026
In Series 4, Max Liebermann has evolved from a curious student of psychoanalysis into a renowned expert whose notoriety has spread far beyond Vienna. By 2026, his relationship with Oskar Rheinhardt has transformed from a professional consultancy into a deep, life-saving friendship, particularly after the dramatic events of the latest season where Max’s life hung in the balance.
Matthew Beard’s Background
Matthew Beard, a Tony-nominated actor, brought a unique vulnerability to the role that has anchored the show since 2019. Known for his work in The Imitation Game and Avenue 5, Beard’s portrayal of Max in 2026 continues to highlight the tension between his Jewish heritage, his scientific mind, and the growing anti-Semitism of the Austro-Hungarian Empire.
Juergen Maurer as Oskar Rheinhardt
Austrian actor Juergen Maurer provides the gritty, grounded counterpart to Max’s analytical approach as Detective Inspector Oskar Rheinhardt.
The Gritty Detective
Oskar Rheinhardt is depicted as a man of action who often struggles with the bureaucratic constraints of the Vienna Police Department. In the 2025/2026 episodes, Oskar’s character is pushed to the limit as he goes on the run to uncover a mole within the state, showcasing Maurer’s range as both a physical performer and a dramatic lead.
Chemistry and Collaboration
The “odd couple” dynamic between Maurer and Beard is frequently cited as the show’s greatest strength. In 2026, their collaboration is depicted as more egalitarian; Oskar has adopted many of Max’s psychological insights, while Max has become more adept at the physical dangers of street-level investigation.
The Liebermann Family
The domestic life of Max provides a stark contrast to the dark murders he investigates, featuring a powerhouse cast of veteran actors.
Conleth Hill and Amelia Bullmore
Mendel Liebermann (Conleth Hill): Best known for his role as Varys in Game of Thrones, Hill portrays Max’s father with a blend of patriarchal pride and anxiety. In 2026, his character remains a vital link to the Jewish community’s perspective on Vienna’s changing political climate.
Rachel Liebermann (Amelia Bullmore): As Max’s mother, Bullmore provides the emotional glue of the family. Her performance in Series 4 was particularly lauded during the episodes where the family must rally to protect a wounded Max.
Charlene McKenna as Leah
Charlene McKenna portrays Leah Liebermann, Max’s sister. Her character has grown increasingly independent across the seasons, often providing Max with a grounded, common-sense perspective that his academic colleagues lack.
Supporting Cast and Recurrent Roles
The world of Vienna Blood is populated by a consistent team at the police station and recurring romantic interests.
The Police Department
Josef Ellers (Sergeant Haussmann): The loyal assistant to Oskar, Haussmann has become a fan favorite for his quiet competence and evolving detective skills.
Raphael von Bargen (Inspector von Bülow): Initially an antagonist to Max and Oskar, von Bülow’s role has shifted toward a more complex, begrudging respect as the stakes for the Empire have risen.
The “Amelia Lydgate” Transition
One of the most discussed casting changes in the series was the transition of Amelia Lydgate from Jessica De Gouw (Series 1) to Lucy Griffiths (Series 2 onwards). In 2026, Griffiths’ portrayal of the English scientist remains a key intellectual foil and romantic interest for Max.

2026 Series 4 Format
