Very mild, including occasional words like "hell" or "s--t".

Mainly animal-on-animal peril (e.g., a leopard seal defending a carcass) and survival-related injuries. Eight Below Movie Review - Common Sense Media

Some scenes are very sad, particularly regarding the injury or death of the dogs.

The film depicts the extreme conditions of the Antarctic, featuring blizzards, freezing temperatures, and the predatory nature of the wild.
