Where do I go next?

So far Caroline and I have been out filming for one day and have in total about one and half minutes of useable footage. We are both in agreement that we need to add to it, however we still are unsure of what our next move should be as we have to be careful that we don't change our film too much. Through talking to people they have suggested that we make things slow and that our titles will fill up the remaining time. I personally feel that this is a big risk and that it would be better to get more footage than we need now, rather than have too little when its too late.

One idea is that we create a blog, and film the last few seconds of our current footage so that we can carry on building the suspense, which also means we have the opportunity to introduce new characters. I believe this could also be good as its a perfectly basic idea. All we need to do it sit down and discuss the details so that when we edit it together there is a flow.
