When my agents said I had been approached to play the president on this show, I said, `So do I have to read it first or will you just say yes now?' For Thelma to be the president is just delightful. It's certainly the role with the most gravitas that I've had to play. I love the way Mackenzie is in the world, how she deals with people, how straight she is and how intelligent and confident she is. It's a pleasure. Geena Davis
