"Peter Jackson, Fran Walsh and Philippa Boyens are indisputably different people, but it is tempting sometimes to think of them as three voices in one person's head. One voice is exuberant (Boyens), one hilariously bleak (Walsh) and one eternally steady and focused (Jackson). It's late Friday night at Jackson and Walsh's house on a bay outside Wellington, New Zealand. The couple's children are in bed, and there are no scenes to shoot tomorrow, so they're lingering over dinner with Boyens, who wrote the "Lord of the Rings" movies with them, as well as their latest epic venture, "King Kong." The wine has been poured—more than once. The conversation has become giddy. "What was the question you asked about the possibility of failure?" Jackson says, attempting to steer the talk toward solid ground. Walsh laughs: "It's more than the possibility. It's the inevitability!" Now Jackson laughs. He tries again: "To live the rest of your life trying to top 'Lord of the Rings' would be a foolish and unsatisfying thing to do. So you set your sights on making a thoroughly entertaining movie so that people are not disappointed."
