I like how this poster gives the impression that the story within the film is real. Here, you notice the poster before the film title. It is made to look like a poster issued by the government, as a result of a virus escaping into the city. It therefore shocks you before you realize its just for a film. This kind of poster makes a film feel like more than a film; it engages the audience by effecting them in their day to day life, taking itself seriously even outside the film and therefore making it seem more believable. This causes more of an excitement to see it.
I like film posters like 'The Good German' where they embrace the period of the film extensively. The poster is made to look like an old film poster, like the ones during the war. This technique, similarly to the '28 weeks later' poster, creates an active audience, outside of the film. The film is a homage to 1940s films, for example, being in black and white, and the poster reflects this too.
My poster could create an active audience by being a missing persons poster, for example.
