One can't deny that Barbara Walters has done it all. She has been a fixture on American television for so many years that anyone under thirty can't recall a time when she wasn't on the television. She hosted the Today Show and 20/20 (for 25 years), and anchored the ABC Evening News. Even at her current age, (born in 1929) she continues to host a successful daytime program, The View.
Morgan Freeman was perhaps the first Black American film star to portray the "gentleman" actor, or show the wise, fatherly nature of a mature, calm man. His many roles have endeared us to his characters as well as his own persona. I loved him in Driving Miss Daisy and The Shawshank Redemption. Additionally, his voice narrations have added authority and credibility to many a documentary effort. He has portrayed God (Bruce Almighty and Evan Almighty), and Nelson Mandela (Invictus). Hard to top that.
