Joan Is an Aspiring Screenwriter and a Business Student at Michigan

Joan is an aspiring screenwriter and a business student at Michigan University Business School to boot. Joan has just written a great new screenplay about the business school experience. Joan is worried about whether her screenplay will be protected if she sends it to all of the major California studios. Joan wrote "Copyright, 2010, Joan Jovial" on the title page.
