TIM --> Similarities and differences in the posters chosen

The posters are similar due to lighting is a major part in all three of the posters, they all use light to create suspense or to outline or show up a particular thing in the poster, "The Strangers" Used candle-like light to light up the protagonist, to show her body language and expression on her face, "Memento" used light to outline the characters on the posters face, using more light with the main character Lenny, maybe to show him in a good light, and the other character on the poster has light only on her face, dark surrounds her, again like I said on the posters review, to maybe suggest she is a bad character. And with "The Machinist", light is used to highlight the posted note so your eye goes to that first. 
Another similarity with each poster I reviewed, is that each one has a tagline creating suspense and adding effect to the poster, Mementos saying "Some memories are better left forgotten" The Machinists one saying "Trevor Reznik is four letters away from the truth" and The Strangers saying "We tell ourselves there's nothing to fear, but sometimes we're wrong"
All three posters, have bold, standing out font, to highlight the title of the film, and they all have the main character or characters names of the film on, to promote the actor/actresses and if they are well known it may promote the film too 
The differences are, firstly each poster is set out differently, Memento uses the use of photographs to cover up the poster, with the characters in as it relates to the film, it is very cluttered with a lot to look at, however The Machinists poster is very plain, with just the title and a posted note generally to look at, and The Strangers poster is pretty much what looks like a screen shot with a bit of extra colour added on to create suspense, so they are both very different but still effective.
Another difference is, the fonts may be bold, but Mementos font is in black whilst the other two are in white, and The Strangers uses a bit of effect on the font where as the other two don't.
