RESEARCH - Convention of film openings

What are the conventions of film openings? 

The conventions of film openings for thrillers are:

• There will be a sense of mood
• The teasers to the story, this is called a hook
• There will be special effects and/or sound effects 
• Sound will be included. This will be to make it scary, atmospheric, eerie. The sound will also build up tension
• The titles. They mostly go in this order; producers ident, directors, stars, name of the film, rest of the cast. The order could change slightly between the stars and the directors. It just depends on who is more famous
• There could be an insight to the characters. this could possibly show the location of the film or the main place in the film and there could also be some narrative but it would not give away the film.  

This what it would look like. A little hook of the film with the tiles.
Sometimes, it could be just the hook and then the title or it could be
the title and then the title.
