A massive dyno high inside Norway's Flatanger cave has resisted some of the world's strongest climbers for more than a decade. Originally explored by Adam Ondra in 2013, the spectacular movement eventually became the defining obstacle of King Kang, a route combining sustained difficulty with an exceptionally demanding final jump. Emil Abrahamsson explores the history of this intimidating project, joins elite climbers attempting its hardest sequences, and investigates how Jules Marchaland finally completed a climb that even Ondra considered beyond his abilities.
The historical background establishes why King Kang holds such a remarkable position in modern sport climbing. Ondra's ascent of Silence and Jakob Schubert's completion of B.I.G. provide context for the cave's collection of extraordinary routes, while Ondra explains his longstanding fascination with the seemingly impossible jump. His admission that he could perform the movement in isolation but could not imagine completing it after the preceding climbing adds credibility to the challenge. Rather than relying entirely on dramatic declarations about difficulty, the presentation allows accomplished climbers to explain precisely why this particular combination of movements is so unusual.
Abrahamsson's personal attempts provide an especially effective demonstration of the physical demands involved. Despite his experience with powerful dynamic climbing, he struggles to reach and control the final hold, discovering how much precision and commitment the movement requires. The explanation of the route's structure is particularly useful: a sustained opening section, a resting position, and an extremely difficult bouldering sequence containing multiple demanding jumps. His acknowledgment that adding even a few preceding movements dramatically changes the difficulty helps viewers understand why completing the dyno alone is fundamentally different from climbing the entire route.
Jules Marchaland emerges as the documentary's most fascinating personality, partly because his climbing achievements seem almost incompatible with conventional expectations. His account of flashing an extremely difficult boulder, despite relatively limited outdoor bouldering experience, establishes his unusual aptitude for powerful movements. Abrahamsson's own struggles on that boulder make the comparison more meaningful, while Marchaland's description of his preparation, confidence, and movement decisions reveals a climber who approaches extraordinary difficulty with surprising composure. Their conversations feel authentic, although viewers unfamiliar with climbing terminology may struggle with the rapid references to grades, holds, and technical styles.
The appearance of Simon Lorenzi introduces another valuable perspective. His attempts demonstrate that exceptional strength alone does not guarantee success, particularly when different body proportions and movement preferences influence how climbers approach the same sequence. The discussion surrounding King Kang's proposed 9b+ difficulty is equally interesting because it acknowledges the subjectivity involved in evaluating extreme climbing grades. Marchaland's aptitude for dynamic movement complicates direct comparisons with endurance-oriented routes, and the climbers recognize that a specialized skill set may determine who can realistically complete the climb. However, the title's suggestion of the world's hardest sport climbing move remains more an expression of elite climbers' assessments than an objectively established distinction.
The documentary also benefits from its quieter moments outside the cave. Fishing excursions, conversations about the local environment, and Abrahamsson's playful frustration over his lack of success provide a welcome contrast to the intensity of elite climbing. Marchaland's recollection of completing King Kang on a day when he was struggling with a headache is particularly memorable. His description of warming up without high expectations, climbing without pressure, and surprising even himself gives the eventual achievement a personal dimension. Ondra's enthusiastic reaction reinforces the significance of the ascent without turning the story into an exaggerated rivalry.
The main weakness lies in the presentation's occasionally scattered progression. The narrative moves between historical achievements, individual attempts, technical explanations, bouldering comparisons, and recreational interludes, sometimes making the chronology difficult to follow. A clearer reconstruction of Marchaland's six-session progression and a more sustained examination of his successful ascent would have strengthened the central story. The closing shift toward Abrahamsson's training for another project also introduces a substantial promotional segment for a coaching company, diverting attention from King Kang just as the documentary should be delivering its strongest conclusion. Nevertheless, the combination of firsthand climbing experiences, candid interviews, and detailed movement demonstrations creates an engaging examination of an extraordinary athletic accomplishment.
Pros
- The history of King Kang, including Adam Ondra's original exploration and the cave's other landmark routes, establishes a compelling foundation for the climbing challenge.
- Abrahamsson's firsthand attempts at the enormous dyno communicate the movement's extreme difficulty more effectively than descriptions alone.
- The breakdown of the sustained opening, resting position, and final bouldering sequence explains why the complete ascent is considerably harder than performing individual movements.
- Jules Marchaland's account of his exceptional bouldering flash and preparation for King Kang offers fascinating insight into his specialized athletic abilities.
- Simon Lorenzi's attempts and the discussion of climbing grades highlight how body proportions, movement preferences, and individual strengths influence performance at the highest level.
- Adam Ondra's openness about his own limitations and enthusiasm for Marchaland's success adds humility and genuine appreciation to the story.
- Informal conversations and fishing excursions provide personality, humor, and a sense of the environment surrounding Flatanger's climbing community.
Cons
- Frequent transitions between climbing projects, historical comparisons, and individual attempts occasionally make the chronology difficult to follow.
- Specialized terminology and rapid references to climbing grades may leave newcomers without enough context to appreciate certain technical distinctions.
- Marchaland's successful ascent receives less detailed, continuous analysis than the importance of the achievement warrants.
- The claim surrounding the world's hardest individual sport climbing movement relies on subjective comparisons rather than a definitive standard.
- The extended closing discussion of Abrahamsson's separate training project and associated coaching promotion weakens the documentary's focus and conclusion.
King Kang's extraordinary difficulty becomes genuinely understandable through Abrahamsson's personal struggles, Marchaland's remarkable abilities, and the informed perspectives of climbers who know the route intimately. Although the storytelling occasionally wanders and the promotional ending feels disconnected, the documentary succeeds in capturing the technical complexity, determination, and camaraderie behind a historic climbing accomplishment. Experienced climbers will particularly appreciate its movement analysis, while broader sports audiences can enjoy a compelling portrait of athletes exploring the boundaries of human performance.
