I usually agree with Michael Moore, but I disliked his blindsided assault on Heston--who greeted him with courtesy, and sat down to be interviewed by someone he knew was opposed to some of his views. Heston came across as a champ, Moore as a blindsiding opportunist. I still agree with him much more than with Heston, but Moore showed no class, Heston a lot.
Sometimes I liked Heston as an actor, sometimes I didn't. He had a tendency to take himself too seriously at times, and his performances sometimes came across as pompous. I think he's fine in SOYLENT GREEN (though no one could have played that last scene convincingly), not good at all in THE OMEGA MAN. As a star, in BEN HUR, for example, he tended to let his neck tendons do much of the emoting, relying on strained, teeth-baring grimaces too often. But as a character actor, he was always very good, even in unlikely roles, such as Long John Silver in the tv miniseries of TREASURE ISLAND directed by his son. It's the one and only time I ever saw Heston come close to being loveable (as opposed to admirable, his stock in trade). He was great in KHARTOUM, Lester's MUSKETEER movies and as Henry VIII in CROSSED SWORDS, that somewhat flaccid version of PRINCE AND THE PAUPER.
I saw him on stage in and as MACBETH, with Vanessa Redgrave as Lady Macbeth. He was good, but he didn't quite have the tragic aura that often works well for performers in that role.
