"Thriller is a broad genre of literature, film and television, having numerous subgenres. Thrillers are characterised and defined by the moods they elicit, giving viewers heightened feelings of suspense, excitement, surprise, anticipation and anxiety. Successful examples of Thrillers are the films of Alfred Hitchcock." In the 1950's, Alfred Hitchcock made a huge difference to the genre of Thriller; he was the first person, who worked behind the genre of Thriller, to use technicolor, as well as making sure that stereotypical blondes played the leading role. Thriller films in this era began to verge on the genre of Horror; he maintained this by adding violence to the films, whilst maintaining the difference between the two very similar, but also very different, genres. The first Thriller film was 'The Lodger'. His films contained a variety of "thrills" throughout, and tend to end with a shock or a plot twist. He is famous for both directing and producing Thrillers. He has a very distinctive way of filming, by using the cinematography to display a variety of emotions, as well as being able to create suspense, tension and anticipation. Stereotypical plots have a modern twist nowadays-this often includes situations that are relevant to modern day society. Music and sounds were used to support in the aid of "heightening the viewers mood", as well as making the audience feel tense and to create suspense. As well as music and sounds, both diegetic and non-diegetic, lighting and colour was available; this allowed the directors to use dark, shadowing lighting to emphasise the dark side to characters.
