Looking at only the male actors that are currently acting, who do you think are the 3 greatest of our time? I have not included actors like Humphrey Bogart, Clark Gable, etc. because it is tough to compare the great ones from different era.
You can use any criteria you want to define greatness, but the way I selected these is -
Consistently great performances in multiple movies. Most of them have won Oscars (some of them more than once), but winning an Oscar should not be the sole criterion for greatness, IMO.
Due to the limit of 12, I had to exclude some deserving actors like Philip Seymore Hoffman, Russell Crowe, Kevin Spacey, etc.
