Ha! I correctly guessed Samuel Jackson. Over a decade ago I read he was the number 1 actor for gross receipts of all the movies any actor had made (don't know if it's still true). I somehow felt that stat would be connected to this one.
Would never have guessed Nicole Kidman for women, though.
I'd never heard that stat about Samuel L. Jackson and find it interesting because I don't think of him as a particularly versatile or prolific actor, though good in his roles and typically well cast. The stat is believable (apart from verifying it) given the massive franchises and singular hits he's landed.
