GONE GIRL
In this first screenshot, we can see Amy lying down with barely any light on her face at all. This lack of light on her face portrays her as a sinister character. If the light was distributed onto half of her face, she'd have two sides to her - however, there is barely any light on her face, showing that she shows very little of who she really is to others, and that a large majority of her personality is hidden. This causes the audience to feel quite uneasy and uncomfortable about her. Due to the rest of the film, they know what Amy is like, and are most likely hoping that her husband does not fall for her tricks again.

In this screenshot, similar lighting is used on the husband's face - an attached shadow is on half of his face, whereas the other side is mostly in light. This differs from the light on Amy's face, as he his face is split pretty equally between shadow and light - this shows that although he too is multifaceted, it is not to the same degree, and when this conclusion is matched with the knowledge gained throughout the film, we realise he acts the way he does due to Amy's own behaviour. Therefore, where Amy's hidden personality makes the audience nervous, as they're not sure what she's going to do next, the hidden schemes of the husband make the audience feel more confident and reassured. It makes them think that he has something up his sleeve, and isn't going to let her win.

In this screenshot, the husband is positioned with light behind him - the source probably being a back light placed quite far away, producing fairly weak lighting. This use of such a light is soft, and presents the atmosphere outside of the room with Amy in as quite safe and welcoming. This juxtaposes with the room she is in; her room is dark, and will be pitch black once he shuts the doors completely. This could show the true reality of her character - perhaps the idea that there is no light to her at all. The audience are, at this point, convinced of Amy's evil personality. It also reinforces to the audience that being away from Amy is much safer than being around her. The light source being behind him could also hint to the audience that the safe, normal world is behind him, and he has turned his back on it. Now, he is stuck with Amy, and thus cannot go back to it.

In this screenshot, the light coming from the ground floor of the house creates a cast shadow of the banisters on the wall - this creates bars, almost like that of a cage. When he passes them, his own shadow is cast among the bars. This presents him as being trapped or imprisoned by Amy - except the restraints aren't physical, they are psychological. He is trapped, but not visibly, so he cannot get help. He has no choice but to stay in the situation he has been forced into, with no escape. This makes the audience feel a degree of sympathy for him, as he has no means to get away from his wife.

The lighting in this shot allows the audience an insight into what he might be thinking, and what he might be feeling. He's in the corner, with light above him - this could show that he craves safety, and wants to get away from the darkness that Amy carries with her. However, his face is almost completely in darkness; this could tell the audience that he has to do something very bad in order to be safe and free from her. This creates enigma code, as the audience is left to think about what he might do, or what he's thinking of. The audience therefore may feel sympathy for him due to the position he's in, and the fact he's being forced to go to such extremes when he isn't a bad person.
I won't use these lighting techniques in my own thriller opening, due to the fact the filming is done outside - but the use of the dark places to imply a lack of safety and foreshadowing that bad things are going to happen (e.g. in the woods) will be something for me to explore by seeing what the natural lighting is like in the location at different times in the day.
DRIVE
The lighting in this shot is sparse - there's just enough of it to see that he's in a car, which highlights immediately the location of the shot, and shows the audience that this might be an important part of his life, or the film in general. The attached shadow on his face makes the audience think that he might not be all he appears to be; it suggests that he has a secret, or is a character with more dimension than we originally see.
This shot is similar to the previous one, but there is a lot less light; this suggests that the character could be almost completely in the wrong, considering he's entirely covered in shadows. The audience is hinted at that he could be involved with something immoral or bad, as innocent people are generally covered in light and thus shown to be open and honest.
In this shot, the lights are unusually low, and this amount of low concentrated lighting seems to cover the character's whole life. This suggests to the audience that he could be involved with something negative that affects his entire life, like crime or such. This increases the eerie feel of the environment, and also creates a more tense atmosphere, like the audience is constantly waiting for something bad to occur as a consequence of his negative involvement that the audience does not yet know about.
The carefully placed patch of light on his back accentuates the scorpion on his jacket. This creates an enigma code, as it draws our attention to it and makes the audience believe that it is significant within the film, and they want to know what it means or what it alludes to. The lighting make sure that nobody misses it, and it is definitely noticed by the audience.
This shot of his apartment is quite eerie and almost depressing; it's in complete darkness, unlike usual homes which have warm, yellow light throughout them. His apartment seems not at all welcoming or safe, showing that it isn't a place where he feels either of those things - welcomed or safe. This is quite sad for the audience, considering it shows the darkness reaches him even at home, and suggests that what he is involved with must be really serious.
