10 Ways Movies Blew Your Mind Without You Even Realising

7. Hans Zimmer's Musical Score Marks The Passing Of Time On Earth - Interstellar

Christopher Nolan is nothing if not a stickler for the finer details of his movies, and he took this to a ludicrous extreme on his 2014 sci-fi blockbuster Interstellar.

When Coop (Matthew McConaughey) and his team arrive on an unstable water planet mid-way through the movie, Hans Zimmer's track "Mountains" begins to play, underscored by a potent ticking motif.

These ticks occur in the track once every 1.25 seconds, and while that might at first seem like a typical metronomic measure for a beat, it also not-so-coincidentally lines up with the film's own time dilation narrative.

It's explained that an hour on the water planet accounts for 7 years passing back on Earth, and as people who did the maths realised, that would mean 1.25 seconds on this planet covers an entire day back on Earth.

The tick already does a fantastic job of enhancing the scene's desperate urgency, but once you know what it truly symbolises, of days slipping away back on a dying Earth, it's even more intense.
