Who had July in the Pope movie pool?

CBS will produce a four-hour TV movie on the life of Pope John Paul II after reportedly receiving the blessing of The Vatican. The biopic will follow the Polish-born pontiff from his early days through his 26 year reign as the head of the Catholic church. No doubt CBS sees a Pope flick as a safe bet for airing during an upcoming sweeps period and the movie will likely get some heavy promotion in the run-up to airing. While no casting has yet been done I can envision some people as being good fits for the lead role. I'm thinking Kelsey Grammer for some reason. Anyone else want to speculate?
