Write or secure a screenplay that focuses on a specific disaster. Disasters can be natural or man-made. Earthquakes, fire storms and floods are examples of natural disasters. Man-made disasters include shipwrecks, nuclear explosions or airline malfunctions.
Create characters that appeal to a wide range of audiences. People watching the film should feel as if they can relate to the people being affected by the disaster. This will enhance the suspense when these characters are in danger.
Establish visually striking set pieces. Disaster films depend on dramatic shots to heighten the suspense. Images of fire, huge waves, asteroids and other disastrous elements will increase the magnitude of the film.
Select music that will enhance the dramatic nature of the film. The music should reflect changes in mood throughout the film. A suspenseful scene, for example, may require a crescendo of loud drum beats. A quiet, reflective scene will be enhanced through the use of soft, melancholy music.
The editing should also reflect changes in mood. Quick, sharp edits, for example, will enhance a chase scene. Slow, steady shots will help the audience focus on a characters' dialogue or on a romantic scene.
