"I Am Legend" - How Can We Infer The Target Audience?

The mise-en-scene, colours and text of the poster for the film “I Am Legend” promote it to a specific audience.  The target audience for the film is a predominantly male audience, from the ages of 12 to middle age.  The post-apocalyptic scenery, shown in the run-down buildings, rubble and hazy sky give the impression of a science-fiction thriller, which would appeal to the male audience.  The idea of a post-apocalyptic setting is confirmed in the caption, “The last man on Earth is not alone,” also suggesting that there is an enemy for the protagonist to fight. The protagonist, Will Smith, is walking confidently through the rubble, ready to save the world.  This enforces the stereotype of the male hero.  The colours of the poster are also a factor determining the target audience.  The dark colours around the edge of the poster suggest mystery and danger, while the gold colour in the center highlight the hero, connoting victory. The bold, capitalized text (conforming to the colour scheme) represents the serious situation/atmosphere.  The skyline in the background sets the film in a big city, a traditional venue for action/adventure films, which would also appeal to the young male audience.
