What Marielle Knows

Julia and Tobias appear to have a comfortable, harmonious marriage and a settled life with their daughter Marielle. That picture breaks apart when Marielle suddenly gains the ability to see and hear everything her parents do, wherever they are and at any hour. What begins as an odd and awkward situation gradually exposes the secrets and conflicts the couple have kept hidden, turning their family life into a tangle of uncomfortable revelations and shifting loyalties.

Frédéric Hambalek directed and wrote the screenplay; Philipp Worm and Tobias Walker produced for Walker & Worm Film and Das kleine Fernsehspiel. It is his second feature, following Mountain Fever from 2016. Laeni Geiseler plays Marielle, with Julia Jentsch and Felix Kramer as her parents, alongside Mehmet Ateşçi, Moritz von Treuenfels and Sissy Höfferer. The German production runs 86 minutes and blends comedy, drama and fantasy.

The film was released in April 2025. On IMDb it holds 6.6 out of 10 from around 600 votes, while on TMDB it has 6.3 out of 10 from a much smaller group of voters, indicating a modest but broadly consistent reception.
