Audrey Hepburn is another celebrity like Charlton Heston who really used her fame and fortune for humanitarian work.

Not sure I would call the NRA humanitarian in any sense of the word, but.... Do see a 2nd Amendment right to bear arms but arms within reason of home self-defense, hunting, and target practice. Many of the weapons championed by some of the NRA gun nuts seem illogical for ordinary people to have.
Heston did make some movies that should be remembered 100 and more years from now.
