Charlton Heston was the face of the biblical and historical epic, in The Ten Commandments, Ben-Hur and El Cid, and won Best Actor for Ben-Hur. The physical presence and the declamatory delivery suited a form built on scale.
The more interesting stretch is the late 1960s and 1970s, when he anchored a run of pessimistic science fiction: Planet of the Apes, The Omega Man and Soylent Green. All three end badly and all three cast him as the last competent man in a collapsing order, which is the epic persona inverted.
He marched with Martin Luther King in 1963 and later became president of the National Rifle Association, a trajectory that made him a contested public figure for the last decades of his life.
Touch of Evil, in which he is miscast as a Mexican official, is worth seeing anyway for everything around him.
