Though the general idea when putting a feature together in the first place is to suspend an audience's disbelief to the point where they can truly immerse themselves in the movie magic going down in front of their very eyes, there's still something tremendously satisfying about peeling back the curtain and discovering how certain big screen moments came to be.
Perhaps even more so when it pertains to an all-time classic piece of filmmaking.
Sure, there's a danger that understanding how certain on-screen pieces of action were pulled off could take away the mystique of some of the most cherished pieces of cinema to ever be pumped into pop culture. But more often than not these glimmers from behind the scenes add even more charm and lustre to what was already a massively adored picture.
From the unexpected truth behind how iconic stare-downs were actually achieved to real-life drama making already awesome sequences that little bit more impressive, you'll likely never see these fine features the same way again once you've got through the following ten entries of factual film gold.
So, let's get to it...
10. Titanic - Neil DeGrasse Tyson Changed An Important Scene
Unless you've been hidden away from modern society for the last two decades, you've likely stumbled across the name "Neil DeGrasse Tyson" and the record-breaking box office smash that was "Titanic".
However, what you may not have realised is that these two entities actually collided a few years ago in the lead-up to James Cameron re-releasing his film in 3-D back in 2012. As the legendarily precise director later explained, maverick astrophysicist Tyson pinged him a "snarky" email explaining that he'd originally made a bit of a c*ck up during one of the movie's climactic moments.
As Rose lay on some driftwood and stared up at the stars, Cameron actually showed off what Tyson claimed to be the wrong field of stars for that position in the Atlantic in 1912. So, ever the perfectionist, Cameron went back to the drawing board and used the correct correlation of stars, as provided by Tyson, for its eventual 15th Anniversary re-release.
This isn't the first time Tyson has dissected a feature in such a way, either, with the astrophysicist poking fun at Gravity's non-floating hair in space and debunking the common trope of freezing humans in order to time travel as nonsense too.
