Short film

I've edited many episodes, mostly half-hour shows that have a lot of live material or montages set to music, again unscripted. They have their own challenges, which I enjoy. But I've always wanted to put together a short film (e.g. 3-5 minutes) of purely scripted material. Something that contains multiples takes to really bring out the story. Something that was completely storyboarded first.

So the question remains: what is the subject? And can I shoot it all myself or do I need to find some cohorts to make it happen?
