There isn't going to be any dialogue in our film opening, as its going to be a chase scene and it just would be irrelevant.
We are going to put in some additional background sounds and delete all of the original sound that goes with the shots, as we want a calm atmosphere at the start before the action begins.
As for the chase scene itself, we are planning to put in some fast paced action music to go with the fast editing we are going to have. It should go quite well.
Finally, towards the end of the film opening we are planning to have a voice over which sums up what has happened in the opening so far. Up to this point, there would have been no dialogue, so it's reasonably important.
