Typical conventions of film posters

From many of the posters I have seen both professional and student there seem to be similar conventions for them all.

• The largest text is usually the title of the film. Standing out so that the audience will be attracted to not only the poster but the title first.
• The main character is usually in the centre and the main image on the poster this is supposed to allow the audience to recognise straight away who the main character in the film will be.
• Posters also usually have the names of the actors in the film as well as who directed it and the name of the company that produced and financed the film.
• There also tends to be some sort of slogan that usually relates to the film sometimes like the film poster above there is a fact that says a bit either about the director or main actor.
• Other examples are below:
