Ideas?

So far I haven't really had many ideas. My first idea that I wanted to run with was to create a film based around a middle aged man who is convinced that he is Elvis reborn. The film would show him performing and going about his day to day life as Elvis, he would then be haggled by a stranger who would shout drunkenly, 'You are not Elvis'. This would have caused the main character to begin questioning his life and struggling to come to terms with his reality that he is not Elvis. He would then stumble through his door where his mum and dad, dressed as Marilyn Monroe and Darth Vader would comfort him and he would go back to his usual life as Elvis.

I felt this idea would work as a short film, but it had too many complications for me to actual be able to construct it. One of these was actors, for my AS piece I was lucky to find actors who fit the role I needed to, but it is very difficult finding middle aged people to be willing to act in a teenager's media coursework, so I've had to replan and think of something I could find an actor for. Another issue with this piece is its similarity to The Crusader and therefore I feel it wasn't original enough to go with.
