I've been a film buff all my life. The onset of the dvd era brought major insights into the whole process via commentary tracks (I recommend listening to as many as you can). I purchased Final Draft about five years ago along with The Complete Screenwriter's Manual by Bowles, Mangravite and Zorn. I strongly recommend both. I am finding that format discipline is sorely lacking with most aspiring writers. This is a shame because an otherwise good story is torture to read without it.
