In 28 days later a virus is spread and eventually 'takes over the world'. In one scene a crow drops blood into a mans eye and he becomes infected. This kind of passing of the virus is the kind of thing we want to go for (except just from human to human). The no fuss way of people getting infected is the point of our film, because we're showing how the virus goes on a journey and is easily spread from carrier to carrier. http://www.imdb.com/video/screenplay/vi4071817497/ this is a trailer for the film and at the beginning you see the shot of the blood dropping in his eye and how he becomes infected.
