I can picture him playing Thomas Jefferson
Don't get me wrong; Stephe Dillane was magnificent as Jefferson in the John Adams miniseries, but it occured to me that if HBO or somebody were to do with Jefferson's life story what HBO did with Adams and, for whatever reason, they were to re-cast the part, I can totally see him playing the author of the Declaration of Independence.
(BTW, it's also funny because in "Angels in America" he references Thomas Jefferson in the final scene.)
