In 2024, the performative creation process of Katharina Grosse’s studio paintings was captured in an experimental documentary film. The production was realized in collaboration with the Wunderblock Stiftung under the direction of filmmaker Claudia Müller. The half-hour film, shot on the foundation’s grounds, was presented in 2025 as part of the solo exhibition “Wunderbild” at the Deichtorhallen Hamburg and during Art Week 2025 at Berlin’s Filmkunst 66 cinema.
