The font of a film is important in setting the scene for the whole film. In films, the font can tell you what genre the film is, for example serif fonts (fonts with little flicks like the one I'm typing in now) are usually associated with more serious genre's such as crime. However, sans serif fonts, without the serif's connotes simple, casual films, like comedies.
The Stepfather's bright blood red typology connotes violence, making the typography look 'thrilling' relating to the film. Both styles show how typography can indicate which sub-genre a film is.
'Fonts convey an emotion without having to say the words' - Neville Brody.
