Through various lighting techniques like infrared and flashlights, the different scenes in the cave are revealed, from dark and vague to clearer views of the character and surroundings. The characters travel through different parts of the cave, which was actually built for the film rather than a real cave, in an attempt to escape. Juno wears more sporty cave attire compared to the others, like Beth in simpler suitable clothing. Props like helmets, headlamps, climbing gear and flashlights are used for the caving activity and to provide light. Diegetic sounds include water dripping, character speech and movement, while non-diegetic sounds are minimized to maintain realism since music wouldn't actually be heard in a cave.
