There are 7 rules you should remember when writing a short film:
1.The shorter the better
A short film can be anything from fifteen second to forty five minutes in length. Make your short film script as possible because the shorter the short,the less costly it will be to produce. Of course, digital technology frees up filmmakers, yet time still costs money, so does feeding a hungry crew, and if your shoot too fast your short film might end up looking amateurish. It has to be cheap but shouldn't LOOK cheap! Plus, if you want to get your short into a festival, then keep it to no more then ten minutes, which is usually 7-8 pages maximum. Why? Because if you short film is longer, it will eat up a longer slot and festivals love to play as many short as possible! You can also create real emotion in just a few minutes.
