This is actually the FINAL version of a puzzle that I inadvertently published called "Sounds Like We Need" the answer to both is the same, but this is the, ostensibly, more polished version. Neither was particularly difficult but the answer is implied from the puzzle not explicitly spelled out. Pick your poison!
REVEAL:
The solve is built upon the "Sounds Like..." part of the title. It implies homophones and indeed there are 4 two named actors:
BEN AFLAC (AFFLECK)
MICHAEL KETONE (KEATON)
ADAM VEST (WEST)
GEORGE CLUNY (CLOONEY)
What these individuals have in common is that they all played the Dark Knight - BATMAN, which answers the meta question.
There are also little Easter Eggs: ROBIN, CAPE, SAGA (The Batman Saga)
