The First Week of Movie Production

So my team and I had finished setting up our schedule for our filming days. We also have location set and ready. But there was a sudden change in the jobs. Instead of being the cinematographer I am now the main character. Instead of working with the camera I'm going to work with Mimi and sound.  We thought we were ready to shoot yesterday but we ended up canceling it due to my teacher's advice. We've finished the shot list and have a clear idea on how we want to shoot the first 5 scenes of the movie. All that's left is to act. Oh but I'm not so good with the acting. Good luck to me.
