Kenneth Lonergan

The A-list actor endured a grueling legal battle that lasted years, watching helplessly as his friend's film became trapped in courtroom drama and studio politics that he called 'completely nuts.'

One of Hollywood's biggest stars was set to take on the role of a lifetime, a part he personally developed and called the best he'd seen in two decades. But scheduling conflicts forced him to make a difficult choice, handing the career-defining performance to a close friend who would go on to win an Academy Award for it.
