Problems With Shooting

As I am the main actor and the Director of my groups short film i have found it really difficult to act and direct at the same time. As a group we have come to the decision that to get the most out of the film we have to re-structure a few things. We have changed the main character this will now be played by one of my friends who has more experience in acting as he did GCSE Drama. Also the roof scenes will now be shot at my house instead of at Nathan's house, it is more convenient. Shooting everything in the same place will shorten the odds of continuity errors.
