Perhaps we should call it the “Queen Elizabeth rule.” The Television Academy has unveiled a few new Emmy Awards rules tweaks, including one that should impact the guest performer categories. Under the new rule, any performer who had previously been nominated or has won in a lead or supporting category can no longer shift to one of the guest performer races in the same role in future years.

That has become a more common occurrence in this prestige TV age, when actors often play a high-profile role for a few years before departing — with the promise of still making short guest appearances in subsequent seasons.
