Mountains was composed by Hans Zimmer for Christopher Nolan’s 2014 science-fiction film Interstellar. The piece accompanies the sequence on Miller’s planet, where extreme time dilation makes every moment costly for the crew. Its clocklike pulse and steadily expanding arrangement connect the music directly with the film’s themes of time, distance, and loss. Short excerpts later became useful in online edits, where creators use the recognizable build to intensify countdowns, looming deadlines, scientific visuals, and scenes involving high-stakes choices.
