4. Back To Back Posters
Back to back posters have been around for decades and I don't understand why. If two people are back to back is that supposed to convey the state of their relationship? Romantic comedies often have posters like this but they don't say a lot about the film apart from presumably show who the two main actors will be. A recent example of this cliche is in the posters for the brilliant 21 Jump Street. However, this was making fun of the cliche itself. This poster type is slowly becoming a classic more than a cliche so it's doubtful that this will become extinct any time soon.
