Trailer analysis

I have recently looked at the trailer for the film St Trinians. This film, like mine, is based in a school and so is very useful for me. After looking at it, I can see that I need to add more students into my trailer as so far there is very few. Also I need more shots in classrooms. I plan to record scenes like this next week. I also found that students wear uniforms to make them look like real students. I will need to add this idea into my trailer to add authenticity and to make the audience believe it is a read school. There is also a voice over so I could consider adding this instead of text over the screen. I plan t record scenes such as these so I can compare them to the trailer.
