Inspired by Make Your Own Damn Movie, Direct Your Own Damn Movie, Produce You Own Damn Movie, as well,as the biography of the Toxic Avenger. Both John Russo take the time to write books.
Among other things books have unlimited special effects budgets. Lloyd also taught me to reuse plots and & characters.
The key to writing a book really is to just write the damn thing: the first is always the toughest. This certainly is not the best book on the craft of writing. It does however talk about methods that have worked for me.
