Paul Newman joked that his salad dressing made more money than his films.
That he was a very good actor will be long remembered and analyzed on movie forums forever. It's more difficult, and perhaps not even necessary, to analyze a actor's character, even based on his good works. A man invents a product or several products solely for the purpose of generating income for the needy. There are no measuring sticks for how decent and honorable that is.
In a profession where the mega-successful frequently seem to waste money and talent on superfluous demonstrations of their wealth, Paul Newman's salad dressing income will stand as a monument taller than his Oscar on how to live successfully.
