As of the selected ranking year, Diane Keaton and Sandra Bullock form a comparison shaped more by career pattern than by any single credit. Commercial scale is another meaningful divider, with the career domestic box office measure giving Sandra Bullock the larger theatrical footprint.

The biggest-hit category sharpens the box office contrast, especially because Diane Keaton's leading film creates the stronger single-release benchmark. Overall, the head-to-head score leans leans toward Diane Keaton, but the strongest context comes from the categories where the gap is clearest.
