This is the statistics for 2009 of how many films of each genre were released in the UK. Out of the 503 films made only 31 were of the suspense/thriller genre. Only a small percentage of the film market is of a thriller genre. One reason why thriller films may not target a big auidence is due to the age restrictions. If the film is 15/18 it loses alot of people e.g people under the age restriction and families.
