Worth noting that there are very few actors who can claim TWO iconic characters. Maybe Harrison Ford (Indiana Jones and Han Solo), Stallone (Rocky, Rambo), Charleton Heston (Ben Hur, Moses-—but Moses was real) but I have trouble thinking of too many.

You're right, there aren't many. But...

A key distinction of your post is that Ford and Stallone played two different iconic characters in two different series of films. There are VERY few that can claim that. For example Sean Connery of course claims James Bond, but while he played many great roles I don't think others were in a series.

I can think of two other actors. Buster Crabbe played both Buck Rodgers and Flash Gordon, and Yul Brenner played Chris in two Magnificent Seven films and The Gunslinger in two Westworld movies. In both actors’ cases the different roles are really the same character.

Probably Mel Gibson as Mad Max and Martin Riggs (Lethal Weapon) and maybe Pacino as Michael Corleone and Tony Montana (except Scarface wasn’t a movie franchise), but still his best known role after the Godfather.

"Worth noting that there are very few actors who can claim TWO iconic characters."

If you count TV and movies, you'd have to include Pierce Brosnan (Bond and Remington Steele) and Bruce Willis (Moonlighting's David Addison and John McClane of the Die Hard series).
