Western legend, Clint Eastwood is second on the list, since the 88-year-old actor was key to the spaghetti-western golden age and now an influential director today.
The study also named Samuel L. Jackson as the most influential actor to date.
Contemporary action stars Tom Cruise and Arnold Schwarzenegger also made the top five, and John Wayne nabbed the No. 5 spot.
Jackson has over a hundred acting credits including countless starring roles in critically-acclaimed films including Jackie Brown, Pulp Fiction, and in the Star Wars and Avengers franchises.
