Watch: A J.K. Rowling book will come to life on HBO

Five years after the last book in the "Harry Potter" series was released, J.K. Rowling's first novel for adults was on the shelves. "The Casual Vacancy" was an instant bestseller, simply because of the name on its red-and-yellow cover. Now the novel has been transformed into a three-part miniseries by the BBC and HBO. It will debut in the United States on April 29.
