Robert De Niro

The greatest actor of all time (subjective judgment). Because if you perform in THAT WAY films like "Mean Streets," "The Godfather Part II" (he acted in Sicilian), "Taxi Driver," "Novecento," "The Last Tycoons," "The Deer Hunter," "Raging Bull," "King of Comedy," "Once Upon a Time in America," "Brazil," "Goodfellas," "Casino," and many more, you can spend the rest of your career just messing around, but you will still remain the greatest actor of all time. Huge.
