The Problem Of Time (In A Film About Time Travel...)

In the presentation today the problem of my film's running time was brought up again. It seems my initial idea of splitting the film into three segments doesn't really sit too well with the brief, so I may have to do some severe editing.
Here's an extremely shorter version of the first half of the pilot.

I don't think this version is anywhere near as good, and doesn't really get across all the information you need to know. I think to shorten the script I will have to re-write large chunks of it rather than simply cutting some lines.
