The acting performances on this list are ranked according to their commercial success (awards), along with the level of skill, versatility and role transformation each actor displayed.

To me, accuracy when making a Top 10/Top 100 all time list is extremely important. My lists are not based on my own personal favorites; they are based on the true greatness and/or success of the person, place or thing being ranked. In other words, an actor’s commercial success (Oscars & BAFTA Awards), and influential greatness through their acting skill and role transformation, is how I ranked the performances on this list.
