<p>I am not a screenwriter,but I do know screen writers. Moreover, I, myself, write best selling books.</p>
<p>I can tell you that most sucessful book and screen writers that I know are very special "cats." Writing a play or book is not something that the average English major does or even can do. Generally, these people have the inborn talent to accomplish this with or without training. The training does help to hone the product or helps to produce ideas on how to sell the product. However, if you are not already writing plays or short stories, you may not be able to learn the craft in college.</p>
<p>In addition, even if you have the talent, you need a great deal of persistance, belief in yourself, and marketing talent to promote your product.
I will leave a screen writer to post here.</p>
