You know it's funny you don't hear much about this.
"Heston campaigned for Presidential candidate Adlai Stevenson in 1956 and John F. Kennedy in 1960. In 1961, in Oklahoma on a publicity tour, he joined a picket line at the segregated theater premiering his movie. During the civil rights march held in Washington, D.C. in 1963, he accompanied Martin Luther King Jr., wearing a sign reading "All Men Are Created Equal." As he often said in speeches, Heston said he helped the civil rights cause "long before Hollywood found it fashionable." Heston planned to campaign for Lyndon Johnson, but was unable when filming on Major Dundee went over schedule." The Link
Really no one else that comes to mind who could carry those epics of yore as did Heston. He made some potentially more idiosyncratic films huge and unforgettable (Planet of the Apes, for one).
Sad to hear it. I had the pleasure of sitting in on a few seminars where he spoke a few times. Super nice man and very patient with the few young radicals who challenged some of his politics.
I, too, was very unhappy with Moore's ambush. Heston was, as far as I could tell, a thoroughly decent human being.
Saw him once. Was on set of a PSA on Alzheimer's being filmed at his house. His kitchen had every cabinet & drawer labelled with what was in it. His dress shirt was tucked into his underwear. He had an American flag hanging on his front gate on Coldwater Canyon (I think that's the canyon).
