Write now I am working on a short, with a man and woman in a relationship as the main characters. However the best actor I want for the guy looks about 20-25. The best actress I want for the woman, looks about 40-45. So it will have to be a cougar/cub type relationship, which is not what I originally intended but will work just as well, with the acting talent, I hope.
I too was in a situation where I wanted to follow a police car for production value, but the car was just too damn fast lol.
