I just posted on another thread that I had heard this but couldn't confirm.
I will remember Heston mostly for two great roles:
1. I remember as a kid seeing the Ten Commandments at the drive-in movie with my entire family. Then when it played on tv I'd watch it again nearly every year.
2. In Planet Of The Apes, he was great as Taylor. The quote you posted Ronnie was very popular and still is. I remember the ending was just awesome at the time. The entire movie was so new and different. Btw, do you remember the character name of the girl that helped Taylor??? It's on the tip of my tongue, but I can't remember it.

Edit: I forgot to add Ben Hur with the great chariot race.
RIP to Charlton Heston
