Quizzical Error

In the latest issue of Entertainment Weekly, they offer "The Great American Oscar Quiz," stating: "We'd like to stump the Academy... and all its many fans, with a pop quiz of Oscar-themed trivia."

Well, they certainly stumped me on Question #5:

What was the only film in which two performers were Oscar-nominated for playing the same role?

Here I thought there were two films in which two performers were Oscar-nominated for playing the same role: Kate Winslet and Gloria Stuart in Titanic and Dame Judi Dench and Kate Winslet (again!) in Iris. Boy do I feel silly!
