Adolfo J. Kolmerer’s The Calendar Killer is a thriller that weaves a gripping premise with social commentary, even if it doesn’t entirely escape the shadow of predictable tropes. Based on Sebastian Fitzek’s best-selling German novel, the film offers a dark, high-stakes story about impossible choices and the fight for survival.

The narrative unfolds through two intertwined perspectives: Klara (Luise Heyer), a woman forced to choose between killing her husband or losing her own life, and Jules (Sabin Tambrea), a night shift operator at a telephone safety helpline who becomes her last hope. This dual structure keeps the tension alive, as the film oscillates between Klara’s escalating danger and Jules’ frantic attempts to save her. The setup is undeniably engaging, and Kolmerer’s direction ensures a moody atmosphere that underscores the film’s darker themes.

What sets The Calendar Killer apart is its unflinching exploration of domestic violence, grounding the thriller in a stark reality that adds emotional weight. Klara’s struggle is as much about her immediate survival as it is about escaping the long shadow of abuse, and Heyer delivers a nuanced, harrowing performance that anchors the film.

However, the film struggles under the weight of familiar genre conventions. The pacing falters in the second act, as twists that should shock instead feel telegraphed. While the central premise is compelling, some of the character decisions and plot developments lean too heavily on well-worn thriller clichés, diminishing the impact of the story’s more innovative elements.

The Prognosis:

Despite these shortcomings, The Calendar Killer remains an entertaining watch, thanks to its gripping premise, solid performances, and atmospheric tension. It may not redefine the genre, but it offers a chilling reminder of the real-world horrors that inspired it. For fans of psychological thrillers, it’s a decent entry, albeit one that leaves room for improvement.
