He was also wonderful opposite Sophia Loren in El Cid.
Another excellent work of his was in the miniseries, "Chiefs" - he played the patriarch of a small southern town called Delano, Georgia. It also starred Wayne Rogers and Billy Dee Williams, and chronicled a serial murderer (played by Keith Carradine) over more than 20 years.
What a career he has had - he was also wonderful as Will Penny - so many more that I can't recall them all.
I remember that show. I loved it. Very suspenseful. I forgot Mr. Heston was in it.
