An opening sequence is a sequence of events that happen in a sequence in order to deliver an appropriate set of events. It also establishes a genre of a film, this is done by the introduction of characters, establishing the setting, and using appropriate props and costumes. Another important element of an opening sequence is creating enigmas, this interests the audience as they want to know what will happen next.  

Days of Grace number 1

My film opening sequence is going to be a horror and thriller.

Its going to be filmed in Darwen at a factory setting.

The mix of thriller and horror is a good combination as it creates an exciting and waning combination to entertain an audience.

Characters - A convicted killer / a swat team.

Costumes - An escaped killer with convict outfit on. A swat team with gear on and M4 rifles. 

Props - M4 rifles / swat outfits / convict outfit / factory / buildings / masks.

My opening sequence will be;

There is an escaped convict, a convicted killer, who is on the run after being heavily guarded and transported to a higher level penitentiary when the vehicle is crashed into and severely damaged, the swat team are stunned as the killer escapes and runs, breaks tie raps and is of. swat team see him running when they quickly come to. And they get to chasing him as he runs into a nearby factory.
