The major difference in the development process of TV and film is that TV writing is much more collaborative, explains writer and psychotherapist Dr. Stacey Simmons. A TV show has multiple writers who work together, while a feature film screenwriter is usually working alone.
For writers looking to break into the industry, there are some hurdles. Dr. Simmons first advises writers to visit Hollywood or New York City, where writers can attend networking events and meet agents face-to-face. This is important, because studios generally will not accept unsolicited material. You have to meet someone who can make sure your writing gets sent along to the right people.
