Overview
- The fourth season of Van Der Valk, which premiered Sunday 2 August on ITV1, is being shown as three weekly feature-length episodes.
- Writer Chris Murray says the new run centres on three homicide investigations including a whistleblower killed under police protection, the murder of an environmental campaigner linked to a missing pop star, and the assassination of a cancer researcher.
- Marc Warren and Maimie McCoy return as Commissaris Piet van der Valk and Inspector Lucienne Hassell, and the creative team kept the pair non-romantic while adding Kim Riedle as Piet’s combative ex, Sergeant Kalie Tenkers.
- Cast and crew say season 4 was filmed on location across Amsterdam with additional shots in Utrecht and The Hague and features larger-scale action, stunts and explosions than earlier series.
- The UK premiere follows a U.S. release in 2024, and some viewers have complained about heavy commercial breaks on ITV and ITVX, a reaction that could shape how audiences watch the new episodes.
