I read the article and what it seems to come down to is that Corday & Co. are accusing Sony of not using "best efforts" or "reasonable efforts" in their representation of Days. This is a basic concept of contract law. The case that's used to teach first-year law students this concept is Wood v. Lady Duff Gordon. In this New York case, the famous judge, Benjamin Cardozo, ruled for Wood, holding that Lady Duff Gordon, a fashion designer and Titanic survivor, had an obligation to make a reasonable effort to fulfill her contract with Wood, an advertising agent who had contracted with Duff Gordon to account for money earned from a line of her clothing. Instead of promoting her clothes, Duff Gordon signed a deal with Sears Roebuck to endorse their clothing line, meaning Wood would get nothing. As for Corday's lawyer, Pierce O'Donnell, he's an experienced Hollywood litigator with a law degree from Georgetown Law School and a Master of Laws degree from Yale Law School.
