"The Emperor's Club" (2002)
From Wikipedia: The Mr. Julius Caesar competition is held in an elaborate room made up to look like a Roman villa. After Masoudi is eliminated..., the competition boils down to a series of questions between Bell and Mehta. In a sense of deja vu, when Hundert notices Bell stumble on a question then recover, he notices that Sedgewick is wearing a tiny earpiece with which he is in contact with a graduate student feeding answers to him. Hundert once again asks an obscure question he first asked his class back in 1973: "Who was Shutruk-Nakhunte?", mentioned on a plaque that all the other students knew about, but Bell, having been a late arrival (or never bothering to look at it), fails to answer.
