Paul Newman
Possibly the most under-rated actor of all. He very rarely put a foot wrong on film and almost his films were great if not superb, with the odd exception.. 'Twilight' EEK! Yes he played on his natural charm and his good looks, but always behind this was great depth and he always brought a real human being alive in his characters.
And not only was Paul Newman one of the greatest movie actors of all time, he was also a great human being, and these days we needs as many of those as we can get.
