Things That Are Essential For a Good Opening Sequence

For a successful opening sequence, you should make sure you; 

- Make it eye catching, show off your production values;

- Taste of the rest of the film, but don't give too much away;

- Don't let it drag out into the film;

- Good soundtrack that works with the film, relates to it if possible;

- Build up e.g. tension or mystery. make the audience want to see more;

- Introduce characters, location, theme or mood, all of these? These are optional;

- Institutional detail. Distribution industry/ production company/ actors etc;

As long as you work with these points in your opening sequence, you should be able to create it in a way you will attract people into the film and encourage them to watch on.
