I really hate this poster. Why? Mostly because it’s ugly. The whole stylised blue waves surrounding the faces of the cast makes for an unseemly contrast. And the blue waves themselves don’t really work. They feel weird, out of place, like they belong in a surfer movie.
Also, the poster does little to make you interested in the movie. It doesn’t give us any sense of what the relationship between the characters is. It doesn’t give you any idea as to why you should care about them or about what they will have to go thorough. It basically tells you nothing.
And why is Terrence Howard the only one laughing? It makes no sense.
Now, this poster is much better:
Still a little too bland for my tastes, but it has several good characteristics. It evokes the period the movies takes place in. The positions of the characters hint at their relationships. And their postures and looks tell us these are people that are serious about what they are doing and who are maybe facing difficulties in order to do it. I think that evoking the period is especially important since the movie seems to also focus a lot on this aspect.
So, not great, but definitely not fake wavy things ugly.
