Concerns
Violence
MediumThe documentary is not centered around violence, but it does include references to death, human remains, and the remnants of human civilization in a somber, reflective context. There is no depiction of active or graphic violence.
The film includes "tantalizing glimpses – a diver discovering a skull underwater" and explores "underwater burial chambers". It also features urban explorer Bradley Garrett who "witnesses the remnants of life in the drain system. People live down there: the undesirable, unseen people above ground making their way down to escape from the elements", and observes "discarded materials: cars, washing machines, and everything our modern world wants to get rid of". Archaeologist Fátima Tec Pool and her team ponder "what horror awaited her ancestors whose torches went out while deep inside the caves".
Witchcraft & Occult
MediumThe documentary touches upon ancient myths, sacred sites, and the spiritual understanding of the underworld, particularly in the context of Mayan culture. This is presented from an anthropological and philosophical perspective rather than depicting active practice of witchcraft or overt occult rituals.
The film "whispers ancient myths" and explores "sacred Mayan caves in the Yucatán". Archaeologist Fátima Tec Pool's journey connects with her Mayan ancestors who "treated the caves as a sacred place". The film's approach is described as capturing not only the physical but also the "spiritual side of our understanding of the hidden world".
Scary & Intense Content
MediumThe documentary, while beautiful, can be intense and potentially unsettling due to its exploration of dark, confined, and mysterious subterranean spaces, as well as its existential themes concerning human insignificance and legacy. It may evoke claustrophobia or a sense of dread for some viewers.
Reviews describe the documentary as "thrilling, unnerving" and state that "agoraphobic viewers might find Underland tough to take". The exploration of "the dark void" and the "fear of the dark" is a central theme. The film features scenes of explorers "crawling through ice caves" and navigating storm drains, which can be visually and atmospherically intense. Sandra Hüller's narration states, "In the earth, we not only place what we love … but what we fear and wish to lose", highlighting the unsettling aspects of the underground.

Anti-Christian Themes
LowThe documentary approaches religious and spiritual concepts, such as ancient myths and sacred sites (e.g., Mayan caves), from an observational and philosophical standpoint, exploring humanity's diverse connections to the 'underworld.' It does not appear to promote explicitly anti-Christian themes but rather presents a pluralistic view of human spirituality and belief systems in relation to nature.
The film touches on how "Myths about underworlds span across cultures and religions" and explores "ancient sacred caves" where Mayan ancestors "treated the caves as a sacred place". Sandra Hüller's narration at times "feels like she is reading scripture from a lost world". While exploring varied spiritual interpretations of subterranean realms, there is no evidence of direct mockery or criticism of Christian beliefs.
Other Notes
Target Demographic
Ages 12+ due to its philosophical and sometimes unsettling existential themes, occasional eerie visuals, and discussions of death or human impact on the environment. While lacking graphic violence or explicit content, the profound subject matter and potential for claustrophobia might be intense for younger children.
Additional Notes
Due to 'Underland (2026)' being a documentary focused on scientific and philosophical themes, many typical narrative content concerns (violence, romance, profanity) are minimal or absent. The primary intensity for parents will stem from the film's atmospheric and existential elements, particularly for viewers sensitive to claustrophobia or discussions of human mortality and environmental impact. The film's deep exploration of 'deep time' and human legacy might be profound but potentially challenging for some younger audiences. While the film premiered at Tribeca in 2025, some sources list its broader release or specific festival screenings in 2026, which is why detailed MPAA ratings or universal age-specific feedback from mainstream parental outlets are not yet widely available.
