When looking at the "John Adams" HBO cast one thing is entirely clear in that HBO was able to put together a group of people that certainly did the miniseries justice. The "John Adams" HBO cast was one that had plenty of distinguished stars as well as some up and comers who all worked hard to bring one of the better historical biographies into shining color. While the cast was almost 100 strong, there were actors and actresses that made up key roles in the drama.
Dillane played John Adam's alternating friend and rival Thomas Jefferson. Dillane was able to show how Jefferson dealt with his own rise to power and the way that he dealt with it once he was truly considered one of the most powerful men in the country.
Morse played George Washington in the "John Adams" mini-series and seemed to adequately carry the weight of the nation on Washington's shoulders. Morse carried off the man who was the first president of the United States quite well.
