I saw him in person once, when he came to Harvard to give his NRA spiel, and I can report that his physical presence was just as remarkable, if not more so, in the flesh as it was on screen. Here, via Dave Kehr and Richard Corliss, is the French critic Michel Mourlet's famous Cahiers du Cinema assessment of the Heston mystique:
Charlton Heston is an axiom. He constitutes a tragedy in himself, his presence in any film being enough to instill beauty. The pent-up violence expressed by the somber phosphorescence of his eyes, his eagle’s profile, the imperious arch of his eyebrows, the hard, bitter curve of his lips, the stupendous strength of his torso - this is what he has been given, and what not even the worst of directors can debase. It is in this sense that one can say that Charlton Heston, by his very existence and regardless of the film he is in, provides a more accurate definition of the cinema than films like “Hiroshima mon amour” or “Citizen Kane,” films whose aesthetic either ignores or repudiates Charlton Heston. Through him, mise en scène can confront the most intense of conflicts and settle them with the contempt of a god imprisoned, quivering with muted rage.
Also worth a look: The tribute that Richard Dreyfuss (yes, that Richard Dreyfuss) penned for NRO (yes, that NRO) when Heston was diagnosed with Alzheimer's six years ago.

He was a terrible actor and a worse person. Glad to hear he finally croaked. I wish it had happened sooner. Did you really think anything Dreyfuss says will abnegate Heston's lack of worth? Dreyfuss is singularly unimpressive as an actor and person, as well. Wake up. Be real. How did you get this gig? I like how having a disease somehow enoble's one. Everybody gets sick and dies, most times slowly and sometimes in a flash. Why does a a dying person take on fantastical characteristic's they never had when the were full of life?
