Pommelien Thijs Announces Netflix Film Adaptation of ‘Knokke Off’ with Belle Perez and Sandra Bullock in Spotlight

Belgian actress and singer Pommelien Thijs has announced a Netflix film adaptation of the popular series “Knokke Off,” also known internationally as “High Tides,” during her third concert at the AFAS Dome in Amsterdam. The announcement was made live on stage and confirmed through multiple Belgian media outlets, including De Standaard, HLN, VRT, Nieuwsblad, and NU, all reporting on the same development on April 27, 2026.

The film will serve as a continuation or expansion of the storylines from the three-season television series, which concluded its third run on VRT MAX in Belgium and Netflix internationally in early April 2026. Thijs, who portrays the lead character Louise Basteyns in the series, made the announcement during her concert performance, marking a significant moment in her dual career as both a musician and actress.

According to the reports, the announcement was accompanied by surprise appearances from Belgian singer Belle Perez and Hollywood actress Sandra Bullock, who were brought back into the spotlight for the special event. While the exact nature of their involvement in the upcoming film has not been detailed in the available reports, their presence at the AFAS Dome concert was highlighted as a notable aspect of the announcement.

The original series “Knokke Off,” created by Anthony Van Biervliet, is a Belgian-Dutch co-production that follows a group of young people and their parents spending summers in the affluent coastal town of Knokke. It explores themes of love, friendship, identity, and the pressures of wealth and expectation, with Thijs’ character Louise grappling with bipolar disorder and the societal demands placed upon her by her family.

The series aired its first season in May 2023 on VRT 1 and Netflix, with the second season premiering in March 2025 and the third and final season released on April 3, 2026, exclusively on VRT MAX in Belgium and via Netflix in other territories. Each episode runs approximately 35 minutes, and the series spans three seasons with a total of 18 episodes.

Produced by Dingie and directed by Tom Goris, with writing contributions from Nele Vandael and Luk Wyns, “Knokke Off” gained significant popularity in both Belgium and the Netherlands, becoming a cultural touchstone for young adult audiences. Its international rebranding as “High Tides” helped expand its reach through Netflix’s global platform.

The transition from television series to film represents a natural progression for the franchise, allowing for deeper exploration of character arcs and narrative closure beyond the episodic format. Thijs’ announcement positions her not only as the face of the project but also as a central creative force in its next phase.

As of the announcement date, no official release date, title, or plot details for the Netflix film have been disclosed by the production team or streaming platform. The project remains in the early announcement phase, with further developments expected to come from official channels such as Netflix, the show’s creators, or the actors’ representatives in the coming months.

For fans of the series, the film offers the prospect of revisiting the world of Knokke and its complex interpersonal dynamics, potentially providing resolution to storylines left open at the end of the third season. The involvement of established figures like Belle Perez and Sandra Bullock, though not yet explained, adds intrigue to the project’s expanding scope.
