20 Things You Didn't Know About Gone Girl

20. David Fincher Shot 500 Hours Of Material

David Fincher is noted for his perfectionism as a filmmaker, and during principal photography on Gone Girl that extended to filming a staggering 500 hours of footage over the course of the 100-day shoot.

That's an average of five hours of footage shot per day, an extremely high amount for a major Hollywood movie given the enormous complexities involved with lighting and blocking a scene before filming can begin.

Given the film's 149 minute runtime, that's a shooting ratio of roughly 200:1 for footage which actually ended up in the final film.

For comparison's sake, Fincher's own The Social Network saw the director film 324 hours, so this is quite an extreme uptick even for him.

According to producer (and Fincher's wife) Ceán Chaffin, he filmed an average of 50 takes per scene. Wow.
