As of the selected ranking year, Harrison Ford and Kevin Costner form a comparison shaped more by career pattern than by any single credit. The category score gives Harrison Ford the broader edge, though the result remains a comparison of career outcomes rather than personal popularity.

The biggest-hit category sharpens the box office contrast, especially because Harrison Ford's leading film creates the stronger single-release benchmark. Based on the available ranking data, the balance leans toward Harrison Ford without turning the result into a subjective judgment of acting quality.
