1. 31 suspense films were released in 2009 and 503 released altogether last year.
2. Action, animation and comedy films account for 52% of box office in 2009 in the UK, I think the reasons why these genres are popular because they appeal to a wider audience as they are family movies meaning it is appropriate for everyone to watch.
3. I believe thrillers account for such a low proportion of UK Box Office because most thriller films are 18+ this is because they include a lot of violence and some psychological issues which can be disturbing for many younger viewers, and mostly teenagers go to cinemas to watch these movies, and this does not allow a great number of viewers.
