Conventions of an Opening Title Sequence (Draft)

The opening title sequence of a film is used by film creators to credit the cast and crew of the film. It obviously involves titles while maybe involving live action scenes. Normally, the order of the credits goes:

• Name of production companies
• Director
• Producer
• Other key crew
• Executive producer
• Top billing actors
• The Movie Title
