Celebrity Meltdowns on the Oscar Podium

James Cameron has never been accused of being shy. In 1998, "The Titanic" director came to the podium unabashedly shouting, "I'm king of the world." Indeed, that was Leonardo DiCaprio's big line, but then Cameron tried to get serious. In a halfhearted attempt to pay tribute to the real Titanic, he called for a moment of silence "in remembrance of the 1,500 men, women and children who died when the great ship went down." Then, the giddy director reverted back to hyperventilating hysteria and yelled, "Now let's party till dawn!"
