Film Voice Over Update

I read the speech out loud to see how long the speech would last - 35.27 seconds. I wanted the speech to be spoken throughout the full of my trailer however, the time scale of the speech is to short. Therefore, I have decided that the voice over will not be a continuous voice over, it will be broken down into sections which will be added over specific parts of the film trailer where they will be best fitted. Some shots, I plan on including match on action, on some shots I plan on showing a visual image that relates to the theme of the voice over (e.g the scientific theme) however, not a direct match on action shot.
