A very interesting look at Heston can be read here.
Odd, the writer seems to be criticizing Heston for not seeking political office like Ronald Reagan did, as if he should have sought office. And I don't agree with his assessment of Heston's talent. Heston could genuinely act. Try to imagine Reagan playing Ben-Hur. Anyone who studies Heston's performances in BEN-HUR and THE BIG COUNTRY can see the fine nuances that director William Wyler drew from him.
