Conventions of an opening of a film

In todays lesson we learnt conventions of an opening, such as introducing the production company logo, introduce the distribution company logo, they often carry a title sequence , the mood and the tone of the film is established through sounds such as music etc. Openings of a film are also intended to hook the audience into the film and this achieved by narrative. We are also introduced to key characters in the film, setting is also introduced through establishing shots. In some movie openings, the production companies logo is edited so that its reflected on the film for example in Transformers 2, the stars on the Paramount logo is replaced with the autobot and decepticon signs.
These edited logos often depend on the budget and hype surrounded around the making and marketing of the film.
As well as the logos, openings place emphasis on characters, those who are introduced in the opening are seen as the more important figures of the film, for example in Train-spotting, most of the characters are introduced during the opening.
If the film is a sequel then the opening will contain a feature that the audience will instantly recgonise, for example in the Shrek series, all of the openings contain a fairytale being read.
