Certification Classification

I think that my short film would take the form of a U. There are no swear words, no violence, no offensive language, no nudity and nothing that could be deemed as unsuitable. The only issue would be is that it is a sensitive subject and the people in the video excluding the staff have to give permission for the video to be shown anywhere, along with permission from the line managers there. This is the reason it is tricky for the video to be online as I signed a document stating I will not show or share the video with anyone before A. showing all of the band members and staff the video and B. get permission from everyone in the video and cut out any unwanted footage that they may deem as offensive or that they don't like. I would still give the film a rating of U in terms of it's content as their is nothing unsuitable or inappropriate.
