Cast choice

The cast are the most important 'prop' in a film as they need to look the part and act the part, for example you couldn't imagine anyone else other than Russel Crowe playing General Maximus Decimus Meridius in Gladiator (2000) because he looks the part as he is the right build to look like a Roman soldier and he doesn't look 'modern' so he is the perfect choice to play the General. So in my film I play my main character a young adult, just like any other teenager from the local area, so it has more realism to it than having a twenty-something playing the character of John. So for the overall point of the narrative to be delivered directly and efficiently it's best to have cast myself or some around my age bracket and appearance.
