RESEARCH - What is the purpose of a title sequence and film opening?

All films have different title sequences. This is because each film opening will establish the genre of the film.

In a film's opening title sequence, we expect to see:

• Ident for production and distribution companies
• (Usually) Establishing shot of location 
• Hint of the narrative (some title sequences are very discrete)
• Title of the film
• Opening title credits
• Characters
• Effects e.g. slow motion, transitions
• Soundtrack
