Trouble shooting list for Preliminary Task

We had a various number of problems which we premeditated before the shooting period. First of all one of our group members didn't have a mobile phone so communication wasn't a 100% therefore when meeting up it would be difficult to locate where one is. However to counteract this we had a specific set time and place for meeting and we also had the team members home number. We also thought that there would be a problem if we didn't have the car because part of the scene was going to be taken in the car, if this occurred one of out team members had a back up car we could of used just in case. The fake blood was another problem if this didn't look real this would definitely hinder our scene. These were the only premeditated problems but having thought of them before shooting we were confident that we would be able to counteract them.
