Well since this is a political message board I think I should point out Andy Griffith's contribution to American Politics in his movie "A Face in the Crowd".
The movie is a morality play on American politics about how demogogues like Hewey Long, Father Coughlin, Joseph McCarthy, Rush Limbaugh, Glenn Beck use the media to build a following and then manipulate that following to advance a particular agenda and how the American public is always wise enough to discover these demogogues for what they are and to discredit them.
To the younger posters on this board who find the propaganda and rhetoric in the media from the Becks, Limbaughs, Madows, Fox News & MSNBC disturbing then "A Face In The Crowd" is a must see. Griffith is brilliant in this role.
