Adapted from a book that is (somehow) even more gripping and exciting than the film, David Fincher’s Gone Girl is the perfect demonstration of exactly what a thriller should be. It gets in your head, keeps you guessing, and when you think you’re onto something, it spins you the other way.

He also has a filmography that boasts the likes of Fight Club and Seven, but nobody’s perfect. Take a look at this deep dive into Gone Girl, which uncovers 10 things that don’t add up, either in terms of storyline or things that somewhat take the audience out of the film’s world.

Amy’s Eye Colour

Throughout Gone Girl, Nick has to look at a variety of publicity shots of his wife, both when he thinks she has gone missing, and when he thinks she is setting him up for her murder.

The description of her listed with her photo clearly says that Amy has brown eyes, even though the woman they’re describing very clearly has green eyes throughout the film.

The Helpline Changes

Perhaps one of the most important things in the hunt for a missing person is consistency. People need to know exactly what details can be relied on as accurate and that these details aren't going to change before their eyes.

When the helpline for tips about Amy is set up, it is introduced as 1-855-4-AMY-TIPS. However, when the audience sees the website set up for the same purpose, the number has changed completely and now says 1-800-FIND-AMY. While perhaps this second number is a lot simpler, why the confusion?

Ink Testing

One of the major issues with Gone Girl was the presence of the diary. It provided the most interesting look at the character of Amy through the brilliant narration, but the fact that the diary was hand-written meant her story could have easily been disproven.

Through forensic testing, it could have been easily revealed that the ink was put there much more recently than the many years prior that Amy implies.

The Disappearing Sweet

One of Tanner Bolt’s most unconventional techniques involves throwing sweets at Nick Dunne every time he is unconvincing during his interviews.

Somehow, this seems to be incredibly effective, if slightly magical. When the first one lands, it is balanced on his collar. When the shot changes for the first time, it’s gone, but when it changes back, it’s right back on his collar.

Sharon Schieber Editing

Sometimes, errors in continuity are easy to figure out. When the Sharon Schieber show is being shown on TV, the rolling news at the bottom of the screen effectively pauses itself and continues from where it left off, even after the shot has moved away.

This is clearly just a case of filming two separate shots and cutting them together, creating a strange issue in continuity.

Tanner’s First Mistake

One of the most obvious things that Tanner Bolt missed, despite being known as one of the greatest lawyers at seeing guilty men go free, was that he didn’t pursue any sort of medical examination on Amy.

She had given herself injuries consistent with rape, but surely there was something fishy about how she was supposedly tied up? Apparently she had miscarried - why didn’t they look into whether she had actually miscarried or been pregnant?

Tanner’s Second Mistake

The second, and far more obvious, issues with Tanner Bolt’s case is how much he ignored the many items Amy had ordered under Nick’s name.

The delivery drivers would have each been able to explain their part of the story: either they had delivered them directly to Amy at her and Nick’s house (thus showing that Amy knew about them and Nick didn’t) or they’d have been asked to take them directly to the shed, which is also obviously pretty suspicious.

Amy Covered In Blood

While in hospital being questioned after her supposed return, Amy is still covered in the blood of her victim.

The fact that she has been seen in the hospital and allowed to change into a clean gown makes it seem very strange that this public event would be allowed to go ahead while she still had the blood of a dead man on her skin. Creepy.

The Blood Positioning

This one would have been rather hard to pull off in one continuity error-free take. When Amy kills Desi, she is brutally splattered with his blood. There is so much blood that if more than one take needed to be made of this scene, it would have been almost impossible to perfectly replicate the splatter.

As such, the blood’s position changed with every change of shot, but fans can let Fincher off for this one.

The Cameras

Amy Dunne

We saw that Amy had managed to avoid the cameras quite well during her time at Desi’s mansion, but surely she didn’t pull it off consistently and perfectly?

Surely they must have caught Desi acting in a relatively normal way? Surely they must have seen her arrive at the house on her own free will? And if they didn’t, surely there was evidence that someone had tampered with the footage?
