I forgot to mention that the playwright who wrote The Audience, Peter Morgan, also wrote Queen. There was an interview with Mirren shown after the play, and she said initially she had not wanted to do The Audience. She'd already played Elizabeth II once, and she'd just finished playing Elizabeth I for a limited series that showed here on PBS, so she felt the need to "dequeenify" herself -- her word. She agreed to a meeting out of courtesy, but when she walked in and saw THAT playwright and THAT producer and THAT director and THAT designer, she asked herself, "Are you an IDIOT?" Passing up the chance to work with those people -- utter foolishness! So she went queening again.
