Location Problems

Being Christmas time that we are aiming to film, we have hit two big obstacles. The first of these is that there is a Christmas tree in the middle of Trafalgar Square, and this could be a problem in the choreography of the scene. We visited it again last night to check on this, and it didn't seem like it would be too much of an issue, but when I passed through last week it seemed to be covered in fencing and obstruction.
The other major issue that we are facing is that over the Christmas holidays a lot of our actors are on holiday or are unavailible. We are considering delaying the production of the film until after the christmas holidays as this would take out both problems at the same time, but with this problem solved, another problem arises. All our cast have important exams in January and they will be wanting to revise in the first half of January. This puts our production even further behind and it appears that filming will commence at the end of January, which means that post-production will be very hurried. This is a risk we are willing to take for the artistry which our actors offer, and so it shouldn't be too much of an issue.
