From Berghain's door to the silver screen: Sven Marquardt takes a leap into John Wick's action-packed universe

Sven Marquardt, the clubland sentry who watches over the door of Berlin's legendary nightclub, Berghain, makes a surprise appearance in the latest John Wick instalment.

John Wick: Chapter 4, first debuted exclusively in theaters on March 24, narrates the gripping tale of battle-worn assassin John Wick (Keanu Reeves) as he strives to liberate himself from the clutches of a clandestine organisation called The High Table. The ensemble cast boasts talents such as Scott Yen, Donnie Yen, Asia Kate Dillon, Rina Sawayama, Cecep Arif Rahman and Brahim Achabbakhe.

Marquardt takes on the role of Klaus, a cartel member, guiding him to a powerful criminal he must eliminate. Klaus's signature line, “I am Klaus” echoes across the film.

The film features several scenes set and shot in Berlin, including an electrifying nightclub skirmish in a setting strikingly similar to Berghain, replete with lavish water displays. The 2023 American neo-noir action thriller film directed by Chad Stahelski and written by Shay Hatten and Michael Finch, John Wick: Chapter 4 is the sequel to John Wick: Chapter 3 – Parabellum that was released in 2019.

In addition to being the world's most famous bouncer, the East Berlin native is also an accomplished photographer who has exhibited his work in numerous locations around the world.
